Personal health assistant HES-CHAT e-skins: integrated mechanosensitivity, electromagnetic shielding, and electrochemical energy storage

Abstract

Flexible electronic skins (e-skins) have emerged as a promising technology for various applications, including health monitoring. In this work, we present a novel study on a multifunctional, conductive hydrogel with integrated ChatGPT as an electronic skin to become a personal health assistant. The polyvinyl alcohol/polyethylene oxide–polyaniline hydrogel e-skin with ChatGPT (HES-CHAT e-skin) hydrogel demonstrated excellent mechanical flexibility and deformation response under certain strain conditions (500%), enabling it to function as a flexible sensor for monitoring human gestures. At the same time, it had good utility in the field of electromagnetic shielding, showing excellent electromagnetic shielding performance (∼59.7 dB) at a thickness of 1 mm. Furthermore, it could maintain a good level of shielding after a long period of time and high tensile deformation (47.0 dB after 56 days of storage, and 42.7 dB after 500% strain stretching). The incorporation of conductive materials with high electromagnetic interference shielding properties improved user safety and device functionality, making the HES-CHAT e-skin suitable for environments with high levels of electromagnetic interference. Additionally, the composite hydrogel demonstrated remarkable electrochemical energy storage properties. Symmetric supercapacitor devices with high volumetric capacitance (7848 mF cm−3 at a current density of 5 mA cm−3) and long cycle stability (81.3% capacitance retention after 10 000 cycles of testing), along with a high power density of 40 W cm−3 and a high energy density of 1090 mW h cm−3, were obtained. This multifunctional conductive polymer hydrogel provided a novel strategy for the development of flexible electronic devices in the field of smart hydrogels.
