Liquid Metal Embedded Elastomers: Electromigration Characterization and Use in Stretchable Sensors
Abstract
In this presentation, we will discuss the use of liquid metal embedded elastomers (LMEEs) in two emerging applications. First, we present a test framework for characterization of LMEE material failure due to electromigration in the presence of high currents or large voltage potentials, and show some initial findings. This test setup mimics conditions found in a variety of applications including electric vehicles, soft solder joints, semiconductor die attachment, and thermal interfaces in packaged microelectronics. Then, we will show stretchable LMEE capacitors that shift the frequency response of RC filters upon strain, enabling a multi-segment stretch sensor with a simple design and electrical interface for shape sensing. The sensor design has applications in wearable electronics and soft robotics.
Biography
Anthony Wertz is currently pursuing his doctorate in robotics in the Soft Machines Lab at Carnegie Mellon University under the guidance of Dr. Carmel Majidi. His research interests lie in the development and control of soft robotic systems, including actuators, sensors, and the use of smart materials, especially in the biomedical and healthcare domains. In particular, his work aims to explore the potential of tunable-friction materials to enhance the functionality of robotic systems.
Anthony is a computer engineer by training. Prior to joining the doctoral program he worked as an embedded software engineer at Lockheed Martin where he was involved in the development of autonomous defense systems. Later he served as a senior research analyst and programmer in the Auton Lab at Carnegie Mellon University where his work spanned multiple domains including medical diagnostics, radionuclide detection, and counter human trafficking.
