About

Rossana Gazia is a materials scientist and sensor engineer whose research sits at the intersection of flexible electronics, smart composite materials, and robotic sensing. Her work has made significant contributions to the development of piezoresistive composite materials, particularly metal-elastomer systems that enable highly sensitive, mechanically flexible tactile sensing devices. Gazia has pioneered the use of copper-PDMS composites that exhibit a remarkable giant piezoresistive effect under compressive stress, making them ideal candidates for next-generation robotic skin applications. Her most cited work, "Smart piezoresistive tunnelling composite for flexible robotic sensing skin" (2013, 33 citations), introduced a microcasting fabrication technique for producing self-standing functional composite sheets, demonstrating an accessible and efficient route to scalable sensor manufacturing. Her complementary 2012 study introduced a low-cost 8×8 pressure matrix sensor with dedicated electronics, further demonstrating the tuneable sensitivity achievable with copper-PDMS systems (11 citations). Gazia's research is notable for bridging fundamental materials science with practical engineering solutions, producing devices that are simultaneously affordable, flexible, and highly responsive. Her contributions have helped establish a compelling framework for tactile sensing technologies relevant to soft robotics, prosthetics, and human-machine interaction research.
