Fig. 2: Principle and electrical characterizations of misrecognition suppression by the shielding layer.

From: Large-area, untethered, metamorphic, and omnidirectionally stretchable multiplexing self-powered triboelectric skins

Fig. 2

Schematic illustration of the working mechanism of UTE-skin operating at single-electrode mode (a) without and (b) with a shielding layer. Numerical calculations of the potential distributions at different distances between the two triboelectric surfaces (c) without and (d) with a shielding layer and calculated voltages versus distances. Comparison plots of the output (e) voltage and (f) current of the sensing nodes, elastic circuits with shielding layers, revealing the suppression of electrostatic interference by the shielding layer. Dependence of the output (g) voltage and (h) current of the elastic circuit on the mass loading fraction of carbon blacks in the shielding layer.
