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.

一种适用于广博的陌生人社会、对每一个人都平等有效且不受空间或情感距离影响的稳定持久的利他主义,即能够体现道德原则普遍性特质的利他主义,不能奠立在缺乏坚定性、稳定性和可靠度的情感主义的基础之上,也不能表现为行为主体纯粹单方面的无私付出——所谓极端理解的利他主义。在宏大的匿名环境里,善意、仁爱、团结的利他主义倾向往往并不呈现在作为个体的行为主体直接的行为动机上,而是渗透在作为社会框架性条件的有控制系统和制裁机制的制度设计里,体现在能够使善好的道德意图转化为对逐利的战略性举措的行为激励上。这样一种对等性利他主义,能够产生出人际互相的行为期待的可靠性,让道德的规范性依靠制度和激励走入现实并发挥其应有的效力。
