About

Bhargav P. Nabar is a researcher specializing in flexible electronics, nanomaterial-based sensing systems, and robotic skin technologies. His work sits at the compelling intersection of nanotechnology and applied robotics, with a particular focus on developing self-powered tactile pressure sensors that could transform how robots and wearable devices perceive physical interaction with the world. Nabar's most notable contribution lies in pioneering the use of ordered crystalline zinc oxide (ZnO) nanorod arrays grown on flexible substrates to create piezoelectric sensing skins. These sensors are capable of detecting spatial tactile pressure variations with a resolution of 1 mm or better, operating across a practical range of 10 kPa to 200 kPa — parameters highly relevant to both robotic manipulation and human-worn garment applications. Crucially, these systems are self-powered, harvesting energy from mechanical pressure itself, eliminating the need for external power sources. His 2014 paper on tactile pressure sensors for robotic skin and sensing garments has garnered 47 citations, demonstrating meaningful influence within the flexible electronics and robotics communities. Through addressable sensor arrays and scalable fabrication approaches, Nabar's research lays important groundwork for next-generation prosthetics, humanoid robots, and intelligent wearable technologies.
