Abstract
Flexible pressure sensors attached conformably to skin are of great interest for wearable electronics and robotic applications. However, effective utilization of such devices often requires them to be stretchable. Herein we report a stretchable pressure sensor based on carbon nanotube - polydimethylsiloxane (CNT-PDMS) nanocomposite. The sensors are based on interdigitated silver (Ag) patterns as bottom electrodes which are connected by a top conductive polymer made of CNT-PDMS composite. The sensors are developed on a PDMS substrate to achieve the required elasticity. The performance of the sensors is assessed by measuring change in the resistance of the device for applied mechanical stimuli. The minimal detectable pressure by our sensor is 500Pa. It is noted that the conductivity of CNT-PDMS composites and Ag electrode spacing are the two critical factors significantly influencing the performance of the sensors.
