Abstract
A flexible sensor includes a first electrode, a second electrode, and a piezoresistive element incorporating piezoresistive composite material arranged between the first electrode and the second electrode. Piezoresistive composite materials include a thermoplastic elastomer (TPE) and a conductive filler material (e.g., carbon), may have an elastic modulus value of preferably less than about 1×10GPa, and exhibit a change in electrical resistance responsive to a change in pressure applied thereto. Exemplary flexible sensors may have a thickness and a feel similar to human skin, may be amenable to simple fabrication techniques (e.g., fused filament fabrication (FFF) three-dimensional (3D) printing or molding), and can be manufactured into user-specific geometries.
