Where this comes from

Abstract

A new concept for high-resolution sensing of touch/load and location in which the number of pixels can be significantly diminished is presented. The technology is based on a flexible substrate with two parallel gold-nanoparticle strips with antiparallel sensitivity gradients for an unpixelated skin strip. The approach exhibits high location and load resolutions.
