BIOGRAPHY
received his BSE in Electrical Engineering from Arizona State University in 2008 and is currently pursuing his PhD in Electrical Engineering with Professor Ali Javey. His research interests include flexible sensors and circuits.

Electronic Skin: Fully Printed Electronic Sensor Networks [BPN747]
Large area networks of sensors which are flexible and can be laminated conformally on
nonplanar surfaces can enable many different applications in areas such as prosthetics, display
technology, and remote stimuli monitoring. For large area applications, printed electronics are
favorable over traditional photolithography and shadow mask technology from a cost and
throughput point of view and we demonstrate proof-of-concept for such a printed “electronic
skin” system by printing a carbon nanotube based thin film transistor (TFT) active matrix
backplane using a reverse roll to plate gravure printing design. This design allows for yields
of up to 97% with printing conducted in an ambient environment and mobilities of up to 9
cm2/V⋅s, the highest reported for a fully printed TFT. Pressure sensors are then integrated
onto the active matrix backplane, which enables mapping of the pressure profile across the
active matrix area. In the future, this could be integrated with other types of sensors and
devices to enable more functionality.
