A Self-Powered Brain-Linked Biosensing Electronic-Skin for Actively Tasting Beverage and Its Potential Application in Artificial Gustation

Abstract

A new self-powered brain-linked biosensing electronic-skin (e-skin) for detecting pH value and alcoholicity of beverages has been realized based on polydimethysiloxane/polypyrrole (PDMS/Ppy) nanostructures. This e-skin (linking to brain and transmitting signal to specific encephalic region) can work as an artificial gustation system for gustatory perception substitution without external electricity source. The sensing units on the e-skin can convert mechanical energy (human motion) into triboelectric impulse efficiently. The triboelectric output can be influenced by pH value and alcohol concentration in common beverages (acidic, alkaline or alcoholic drinks), which can be treated as the bio-chemical sensing signal. The bio-chemical sensing behavior arises from the triboelectrification/bio-chemical-sensing coupling effect. The biosensing e-skin is simply linked to brain of mouse at primary motor cortex area, and the inputting signal can take part in the mouse perception and thus realize behavior interventions, e.g. shaking legs. This work can provide a novel direction for developing artificial gustation e-skin and self-powered brain-machine interaction system with low cost.
