However, to bring these devices to market, they require a reliable built-in power source that can maintain stable output voltage, charge/discharge capabilities, and cycle life. Unfortunately, complex cell configurations have hindered the development of stretchable batteries. To overcome this, a fully stretch-rechargeable battery with a sandwich configuration is fabricated. The cathode layer comprises electrically conductive poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and a redox-active TEMPO-substituted polymer, while the anode consists of a carbon nanotube layer deposited with zinc metal. By sandwiching a hydrogel between these two layers, a rechargeable battery is created that is attachable to human skin and <40 µm thick. This thin device offers a promising voltage of 1.8 V and is robust against repeated stretching, liquid leakage, and self-discharging reactions induced by oxygen. This study is expected to open up new horizons for e-skin and stretchable electronic fields.fully stretch-rechargeable batteries | gel-state electrolytes | PEDOT:PSS-based cathode electrodes | SWCNTs/zinc anode electrodes[SDGs]SDG7[SDGs]SDG12journal article10.1002/adsu.2023000802-s2.0-85153482684WOS:000976032000001https://api.elsevier.com/content/abstract/scopus_id/85153482684
