What is it about?

Piezoresistive materials change their properties when their shape is changed. In this article we introduce a new technique to evaluate these changes in real time and suggest a possible application that could have far reaching implications.

Why is it important?

There are many methods for testing materials, but few methods have been introduced that test both the material and electrical properties at the same time. The main goal in this work is to characterize a soft piezoresistive layer in both tension and compression to enable a model system for a piezoresistive tactile force sensor and a characterization platform.
