This paper presents a discussion on the method, mechanism, and application of adhesive hydrogel in enhancing epidermal signal,focusing on the interface between hydrogel and skin. Due to its excellent conductivity and high adaptability to the skin, the hydrogel is exceptionally suitable for detecting human-machine interfaces, particularly epidermal electromyographic ***, the detection of the high epidermal signal is hindered by the gap and low adhesion between hydrogel and skin. This paper addresses these challenges by introducing approaches to reduce the interface gap and increase interface adhesion, thereby enabling the development of hydrogel-based epidermal signal detection arrays with enhanced resolution and detection performance.
