Polymeric foams for flexible and highly sensitive low-pressure capacitive sensors

Highly sensitive foam sensors High sensitivity is a critical feature for flexible pressure sensors and a novel and low-cost emulsion method has been invented to make capacitive sensors with higher sensitivity. A team of CNRS scientists from France led by Prof Annie Colin develops an unconventional a...
