Summary: A novel non-toxic redox couple of SO42-/SO32- is introduced to create a stretchable, flexible gel thermoelectric device with a high Seebeck coefficient of 1.63 mV K-1 at the optimal redox couple concentration of 0.1 M. The hybrid structure formed between PEDOT: PSS and SO42-/SO32-ion-promoted crosslinking PVA network contributes to the superior tensile/compressive stress and deformation at break of the hydrogel electrolyte. By doping additional electrolyte ions, the gel exhibits favorable ionic conductivity and thermoelectric performance. Moreover, the PVA-SO4/3 2-hydrogel demonstrates the ability to harvest biothermal energy for operating small electronics at body temperature, showing potential for green sustainable self-powered wearables.

Summary: This study reports a bioinspired sensor and actuator created using a conformable electrode interface on a Venus flytrap. The conformable electrode, with an adhesive hydrogel layer, has low impedance, stretchability, biocompatibility, reusability, and transparency for normal chlorophyll activity. By capturing the stimulated action potential signals from the upper epidermis of flytraps, a plant sensor matrix has been demonstrated, which can guide honeybees by touch during nectar collection. Furthermore, autonomous on-demand actuation on a flytrap is achieved through frequency-dependent action potential modulation triggered by a triboelectric nanogenerator.
