microelectromechanical systems MEMS (micro-electromechanical systems) is the technology of microscopic devices incorporating both electronic and moving parts. MEMS are made up of components between 1 and 100 micrometres in size (i.e., 0.001 to 0.1 mm), and MEMS devices ...

(MEMS) started in the early 1990s with the development of new materials for

microbolometers A microbolometer is a specific type of bolometer used as a detector in a thermal camera. Infrared radiation with wavelengths between 7.5–14 μm strikes the detector material, heating it, and thus changing its electrical resistance. This resista ...

for room-temperature infrared detection. This work set the foundation for IR detectors on flexible substrates. The group demonstrated the first IR microbolometer array on a polyimide substrate with performance comparable to those on silicon substrates. Based on the success of this IR radiation detector work on flexible substrates, the group expanded to other sensing functionalities like flow, tactile, pressure, force and most recently acceleration. Integration of sensors on conformal substrates necessitated the group to initiate die-level encapsulation for flexible device packaging. Today, the group is focusing on multifunctional, conformal

s). Most recently, the same model has been revised to account for low-frequency noise observed on multi-stack gate MOSFETs, specifically high-k dielectric gate oxides. The research group has also investigated and developed noise models for polysilicon emitter bipolar transistors, lateral pnp bipolar transistors and SiGe heterojunction bipolar transistors. One of the contributions of the research group is the demonstration of random telegraph signal (RTS) noise as a non-destructive characterization and reliability tool in nanoelectronics. Today, this research thrust area is investigating the effect of extended drain region on noise and reliability of LDMOS structures. Butler is a Fellow of the
