Title:  Sensor Integration: What does it mean and what are its benefits?

Abstract:  The first decade of this millennium was primarily marked by stand-alone Micro-Electro-Mechanical Systems (MEMS) based sensors enabling simple applications that were developed for smartphones and other consumer products. Those sensors offered decent performance and were quite simple without any embedded functions or features. The second decade has been the era of improved performance, price reduction, lower power consumption, shrinking package sizes and higher integration of MEMS sensors. The demand for lower-power MEMS sensors started in the early years of this decade and this requirement was aggressively pushed upon MEMS sensor suppliers by major OEMs of these sensors. This led to a significant power consumption reduction in MEMS devices, e.g. by 2 orders of magnitude in an inertial measurement unit (IMU). As the size of sensors has been shrinking, multiple application algorithms continue to be developed, and new sensors enter the market; sensor integration is a logical consequence of these advances. “Sensor integration” is a broad term, and it is important to understand the context in which this term is being used. Sensor integration can take place at the system, chip, or die level, and it could refer to an integration of hardware components or a combination of both hardware and software components. This presentation will dive into the latest advances in sensor technology that has led to great performance improvements, significant power consumption reduction and the integration of multiple sensors serving various markets. It will also discuss different scenarios of sensor integration.
