The collection of physiological signals as well as the electrical stimulation to the biotissues are significant but challenging. There is a huge gap between the living systems and electronics. Biotissues are wet and soft, while electronics are dry and relatively stiff; biotissues conduct ions, while electronic materials often conduct electrons. As a result, forming a stable interface for bidirectional electrical communications between electronics and the living systems is difficult. In this perspective, we review recent landmark progresses made in this field, and propose a few future directions that scientists may further work on.
生理信号的采集以及对生物组织的电刺激意义重大但颇具挑战性。生命系统与电子设备之间存在巨大差距。生物组织湿润且柔软，而电子设备干燥且相对坚硬；生物组织传导离子，而电子材料通常传导电子。因此，在电子设备与生命系统之间形成用于双向电通信的稳定界面十分困难。从这个角度出发，我们回顾了该领域近期取得的具有里程碑意义的进展，并提出了一些科学家们可能进一步研究的未来方向。
