Professor Songbin Gong and researchers from the Department of Electrical and Computer Engineering have developed a design strategy and method for fabricating efficient piezoelectric micro-machined ultrasonic transducer (pMUT) optimizing both ultrasonic transmitter and receiver performance in a combined platform. Currently, there are two leading material types for pMUTs : ferroelectric perovskites with solid solutions containing PbTiO3, like PZT and PMN-PT (primarily used as transducers ) and the non-ferroelectric structures such as AlN (primarily used as sensors). This balanced ultrasonic transceiver can be implemented in miniature ultrasound applications, specifically in consumer electronics for gesture recognition, biometric sensing and occupancy sensing.

Researchers at the University of Illinois have developed ultra-flexible heterostructures made from 2D layers of van der Waals bonded materials. The heterostructures retain the optoelectronic properties of their constituent layers, but offer tunable mechanical properties which can include flexibility rivaling that of lipid bilayers. Applications for this technology include MEMS devices and flexible, stretchable, and conformal circuitry, including reconfigurable 2D devices and folded/curved/crumpled nanostructures.
