Abstract: A textile-based sensor includes a textile triboelectric nanogenerator sensor attached to and overlying a textile piezoresistive sensor, wherein the textile triboelectric nanogenerator sensor is configured to generate an electrical signal indicative of object contact force and/or frequency with the textile triboelectric nanogenerator sensor, object material, and object surface morphology or texture, and the textile piezoresistive sensor is configured to generate an electric signal indicative of the applied external pressure to the sensor, wherein the textile triboelectric nanogenerator sensor overlies the textile piezoresistive sensing.
