开发无需额外电源即可在日常生活中永久使用的生物电子学是一个重要的研究目标。为此，已经报道了无数基于能量收集的永久性系统；然而，仍然存在限制，例如对特定安装和线路连接的限制。在这里，我们提出了一种基于身体介导的能量转移的新型生物电子学，用于零功率离子释放和电刺激。身体介导的生物电子学（BMB）是一种新系统，可将各种人类活动（例如行走、使用笔记本电脑）产生的电能通过人体传输，而不会造成能量损失。为了将 BMB 应用于人体皮肤，使用生物相容性且具有皮肤粘附性的软离子扩散水凝胶（IDH）作为生物电极。最后，将具有离子电渗结构的IDH组成的BMB贴片应用于人体，在日常生活中实现零功率电刺激以及活性离子发射。
Development of bioelectronics that can be used permanently in daily life without additional power sources is an important research goal. To this end, myriad permanent systems based on energy harvesting have been reported; however, there are still limitations, such as restrictions regarding specific installations and connections to lines. Herein, we present a new type of bioelectronics based on body-mediated energy transfer for zero-powered ion release and electrical stimulation. Body-mediated bioelectronics (BMB) is a new system that transfers electrical energy generated by various human activities (e.g., walking, using laptop) through the human body without energy loss. To apply the BMB to human skin, a biocompatible and skin-adhesive soft ion-diffusive hydrogel (IDH) was utilized as the bioelectrode. Finally, a BMB patch composed of IDHs with an iontophoretic structure was applied to the human body, and zero-powered electrical stimulation as well as active ion emission were implemented in daily life.
