As director of the Center for Bio-Integrated Electronics at Northwestern University, Professor John A. Rogers explores soft materials for conformal electronics, nanophotonic structures, microfluidic devices and MEMS, all with an emphasis on bio-inspired and bio-integrated technologies. During his keynote at FLEX and MEMS Sensors Technical Congress 2019, February 18-21 in Monterey, Calif., Rogers will present examples of the diverse, novel classes of biocompatible electronic and microfluidic systems with skin-like physical properties that stem from his work in materials science, mechanical engineering, electrical engineering and advanced manufacturing. SEMI’s Maria Vetrano caught up with Rogers to discuss his research, which has already been commercialized by companies such as L'Oréal Group.SEMI: What is the concept behind skin-interfaced electronic and microfluidic devices?ROGERS: Biological systems are mechanically soft, with complex, time-dependent 3D curvilinear shapes. Modern electronic and microfluidic technologies are rigid, with simple, static 2D layouts. We believe that eliminating this profound mismatch in physical properties will create vast opportunities in microsystems technologies (electronics, optoelectronics, microfluidics and microelectromechanical devices) that can intimately integrate with the human body for diagnostic, therapeutic or surgical functions. Skin-like devices that assess blood-glucose levels in real-time or continuously monitor the vital signs of infants in neonatal intensive care are just two examples of non-invasive, wirelessly connected biocompatible devices with the potential to dramatically improve quality of life.SEMI: What are some examples of commercially available biocompatible/microfluidic wearables that have leveraged your research?ROGERS: We’ve been fortunate in that we have been able to translate some of our ideas into commercial products for broad deployment in both life-enhancing and potentially life-saving applications. In sports and fitness, our skin-interfaced microfluidic systems form the basis of soft devices that capture, store and perform in-situ chemical analysis of sweat. These devices have been launched as products in two different categories – cosmetics and athletics – with two global brands. As an example of the former, L’Oréal Group just unveiled at CES 2019 My Skin Track pH, a thin, flexible version of this technology, designed to determine skin pH from measurement of sweat pH. Once armed with this information, L’Oréal customers can choose skincare products matched to their personal body chemistry. See the video on this device. Notably, a globally recognized consumer brand will reveal a product for athletics around the time of the 2019 Super Bowl on Sunday, February 3. A look inside My Skin Track pH, which uses Rogers Research Group technology from the Center for Bio-Integrated Electronics at Northwestern University Our technologies also have applications in clinical medicine and rehabilitation, including soft, skin-interfaced wireless sensors used to assess patient progress in stroke rehabilitation. In contrast with conventional, wired sensors that tether the patient to external boxes of electronics (a design that makes such devices impractical for in-home use), or conventional wearables that are confined to the wrist, our systems apply to the skin like a BAND-AID, and are described as “imperceptible” by stroke patients who are using them during rehab. These platforms measure speech, swallowing capability, movement of limbs, sleep quality, walking and balancing. Healthcare professionals can use the information collected to continue to monitor patients when they leave medical facilities, to understand how patients function in the real world. See video.SEMI: What work are you doing beyond flexible devices?ROGERS: We are pursuing devices that are unique not due to their soft mechanics, but due to their extremely small sizes. A good example is My Skin Track UV, which we recently commercialized with L’Oréal’s La Roche-Posay. This millimeter-scale, wireless, battery-free platform for digital UV dosimetry measures UV exposure dose continuously in real time and provides user access to this information via a smartphone app. My Skin Track UV is now available at all Apple stores across the U.S. and through the Apple website. See video. L’Oréal’s La Roche-Posay My Skin Track UVOther biocompatible/microfluidic devices based on our technology provide functionality that can save lives. Hydrocephalus patients suffer from a condition that, if unchecked, leads to excessive buildup of fluid in the brain. If left untreated, the resulting pressures can prove fatal.Hydrocephalus is treated with shunts, which drain accumulated fluid away from the intracranial space to a distal part of the body, often the abdomen. Unfortunately, however, shunts have a nearly 100 percent fail rate over a 10-year period, and testing them typically requires an MRI, CT scan or even surgery. Our technology serves as the basis of a bandage-sized, skin-like sensor that applies to the surface of the skin on the neck. Within five minutes of placement on the skin, the sensor can test non-invasively to determine if fluid is flowing through the shunt. The net result uniquely supports the rapid evaluation of shunts from home or other non-medical settings. The devices free patients from the constraints of hospitals, giving them a greater sense of security and independence. See video. SEMI: What would you like FLEX and MSTC attendees to take away from your presentation?ROGERS: I would like attendees to know that biocompatible microfluidic and electronic wearables that are flexible and conformal to the human body are no longer risky futuristic technologies that exist only in academic labs: They are emerging right now as key products in commercial markets for flexible hybrid electronics (FHE) and MEMS/sensors. Our group alone is anticipating deployment at the scale of tens to hundreds of millions of units in the markets in which we are seeing traction over the next five years. We believe that the broader area will become a multi-billion-dollar market opportunity in five to 10 years.John Rogers, Ph.D. will present Soft Electronic and Microfluidic Systems for the Skin at FLEX/MSTC on Tuesday, February 19 at 10:30 am.Register today to connect with him at the event.

Jason Jelinek, a software technical manager at John Deere Electronics Solutions, has parlayed his more than two decades of embedded software engineering experience into commercializing controls and sensing technologies for rugged/harsh environments, including agriculture/off-road and aerospace. During his keynote at the upcoming FLEX and MEMS Sensors Technical Congress 2019, February 18-21 in Monterey, Calif., Jelinek will address the driving need for advanced sensing technologies that will fuel the continued growth of autonomy in agriculture.SEMI’s Maria Vetrano asked Jelinek to help FLEX/MSTC attendees understand his vision of autonomy in agriculture, which heavily leverages advanced sensing technologies to help farmers master equipment logistics, handle vehicle- and fleet-level operational efficiency, and manage the entire lifecycle of crops.SEMI: Did autonomy in agriculture start with autonomous equipment, such as tractors and combines?JELINEK: Automation, the first step on the road to autonomy, has been occurring in agriculture for a long time. Over the past 100 years, automation has dramatically reduced manual effort and simplified jobs in farming, allowing operators to focus more on administrative and other aspects of their work.The evolution of the combine is a good example of automation in agriculture. Long ago farmers would use a scythe to cut down the crop before bundling or stacking it up. Later they would manually thresh and winnow the crop to get the grain. Over time, we developed windrowers to cut the grain, threshing machines to separate the grain from the chaff, and winnowing machines to get only the grain. Combines now “combine” all those steps to go from grain on the stalk in the field to grain in the hopper. One person in a combine can do the work that once required many people and animals — all in a much shorter timeframe. We are now looking at automating harvesting to maximize yield and reduce fuel consumption. The AUTOTRAC feature on John Deere machines is a recent example. AUTOTRAC divides a field into rows based upon the parameters of the machine in operation, supporting hands-free driving with very high accuracy. It allows consistent, accurate rows for tilling, planting, crop treatment and harvesting, saving considerable time, improving overall quality and freeing the operator to do other work while in the vehicle.The Exact Emerge and Section Control features (which also use AUTOTRAC) will spur greater future autonomy. Control over both the seed spacing (Exact Emerge) and when the machine drops seeds (Section Control) prevents overseeding and provides the right seed-spacing for optimal crop production.As we look to the future, sustained growth in automation of jobs will enable the development of fully autonomous equipment. Currently, however, skilled operators are still closely involved in job management and execution. To realize greater autonomy, we will need machines that make the decisions once made by people.SEMI: How will autonomy in agriculture change the ways that we grow and harvest food — and even affect when we sell it?JELINEK: Autonomy will lead to more efficient production, reducing fuel, fertilizer, herbicide and water requirements. It will also enable fewer people to do more of the work.Let’s start with conditions that are hard, even impossible, to control: weather and staffing.While farming is still tied to the weather — and will remain so for some time — more efficient operations will allow tilling, planting, spraying and harvesting of fields to occur in shorter time windows that more easily match conducive weather conditions.There is also a human-resource issue: The agricultural industry must compensate for population decline in the rural areas where farmers operate. Doing more with less is essential for agriculture to continue to meet the rising food and clothing demands of the world’s population.SEMI: To what degree will we see artificial intelligence in autonomous agricultural systems?JELINEK: While autonomous systems had their start at the vehicle level, they will one day move to the entire fleet, providing suggestions on when the owner should execute operations. Autonomous systems may also help owners to decide when to store or sell crops, based on market conditions, operating costs and desired margin levels. That’s the initial level of artificial intelligence that I foresee.SEMI: How can sensing improve autonomy in agriculture?JELINEK: The challenges we face in agriculture are many, but technology will help us meet them. We must transfer responsibility for operations and decision-making from the skilled operator to the intelligent machine. Through increased use of sensing, we can gather large amounts of data, which autonomous agricultural systems will process, communicate and interpret to streamline jobs and boost agricultural production.SEMI: What would you like FLEX/MSTC attendees to take away from your presentation?JELINEK: I would like FLEX/MSTC attendees to understand the environment in which agricultural sensors need to operate. We need sensing solutions that will survive and thrive in rugged, outdoor variable environments to support the automation that will fuel autonomy.I would also like to engage suppliers in the application of current technology to meet our sensing needs.Jason Jelinek will present Autonomy in Agriculture at FLEX/MSTC on Tuesday, February 19 at 9:00 am.Register today to connect with him at the event.

4 Key Takeaways from SEMI Taiwan Member ForumThe rapid development of artificial intelligence (AI) has accelerated the digital transformation in various industries and has now fused with Internet of Things (IoT) to exploit the value of both technologies in reshaping the electronics industry value chain. As it emerges from the shadows of its parent technologies, AIoT is giving rise to new opportunities in manufacturing, healthcare, transportation, and even energy. AIoT is fast rising in prominence as an enabler of key electronics manufacturing process improvements and the creation of add-on value to existing products – both critical to the success of many businesses.SEMI and the SEMI MEMS Sensors Industry Group (SEMI-MSIG) held a technical forum on smart sensing and its applications in AI and AIoT, inviting renowned experts in sensors and edge computing to share in-depth insights into the latest AIoT technologies and applications with more than 100 industry professionals in research and development, marketing and sales. Here are four key takeaways from the SEMI Taiwan member forum.1. Steady Growth for Global Sensors MarketThe global sensors market’s steady growth is expected to expand at a CAGR of 6.6 percent from 2017 to 2023, with Asia driving the biggest gains and automotive leading the segments – including healthcare and education – with the strongest growth. Automotive alone is expected to reach US$34 billion in 2023.2. Integration Critical to MEMS Sensors DesignsWith AI booming, MEMS sensor designs need to drive toward greater integration —not only integrating data collection with sensors, but also streamlining data processing on the backend – making 3D models of today’s MEMS mechanical designs critical. The differences between 3D and entrenched 2D models are dramatic, elevating the importance of specifying manufacturing steps in MEMS designs. As new sensors and applications continue to emerge, companies that develop the most powerful integrated designs will win. 3. Growth of Smart Voice-Control Applications to ExplodeAIoT is also accelerating the development of smart voice-control applications and the rise of new related business opportunities. Just 50 million voice-controlled devices shipped worldwide in 2017, a number predicted to swell to 436 million in 2021 with smart home devices such as set-top boxes and smart TVs the major growth drivers.4. AIoT Eyed to Make Human-Robot Collaboration SafeSafety is an essential feature for human-robot collaboration. Tactile sensing technologies give robots a layer of “skin” with capabilities rivaling human touch. To ensure humans and robots work together safely in work environments, sensors on this layer of skin are concentrated – less than 8mm apart, equivalent to the width of a human finger, with a response time of less than 5ms on contact. More than 4 million robots worldwide are expected to be upgraded with these sensing technologies and are on track for deployment in pilot plants in the next three years.SEMI-MSIG is committed to strengthening connections across all sectors in the MEMS and sensors supply chain, working closely with the industry to accelerate the development of related technologies and applications in both mature and emerging markets. In addition, SEMI-MSIG hosts regular events to inspire business opportunities and technology exchange for innovative applications, while enhancing the visibility of members among global customers and partners to help them forge new partnerships.
