Abstract
A strain sensor fabrication and its use as flexible elastic heart strain sensors in form of a Wheatstone bridge are described. All arms of the bridge are nanocomposite based strain sensors. The silver selenide nanocomposite is especially developed by simple rubbing in method where the nanomaterials such as carbon nanotubes (CNTs) and Ag2Se nanoparticles are embedded into a porous rubber. This is a low cost easy to make strain sensor that has excellent resistance to humidity and temperature.
