Sensors can measure both strain and temperature or measure force without affecting touch Electronic skins (e-skins) are flexible electronic devices that emulate properties of human skin, such as high stretchability and toughness, perception of stimuli, and self-healing. These devices can serve as an alternative to natural human skin or as a human-machine interface (1–3). For on-skin applications, an e-skin should be multimodal (sense more than one external stimulus), have a high density of sensors, and have low interference with natural skin sensation. On pages 961 and 966 of this issue, You et al. (4) and Lee et al. (5), respectively, report advances of skin-like electronic devices. You et al. present a stretchable multimodal ionic-electronic (IE) conductor–based “IEM-skin” that can measure both strain and temperature inputs without signal interference. Lee et al. describe an ultrathin capacitive pressure sensor based on conductive and dielectric nanomesh structures that can be attached to a human fingertip for grip pressure and force measurement without affecting natural skin sensation.

越来越少的电子皮肤传感器

传感器可以在不影响触摸的情况下测量应变和温度或测量力 电子皮肤（e-skins）是一种灵活的电子设备，可以模拟人类皮肤的特性，例如高拉伸性和韧性、刺激感知和自我修复。这些设备可以作为天然人体皮肤的替代品或作为人机界面 (1-3)。对于皮肤应用，电子皮肤应该是多模态的（感知多个外部刺激），具有高密度的传感器，并且对自然皮肤感觉的干扰低。在本期的第 961 和 966 页上，You 等人。(4) 和 Lee 等人。(5) 分别报告了类皮肤电子设备的进展。你等人。提出一种可拉伸的多模态离子电子（IE）导体“IEM-skin”，可以在没有信号干扰的情况下测量应变和温度输入。李等人。描述了一种基于导电和介电纳米网结构的超薄电容压力传感器，该传感器可以连接到人的指尖进行抓握压力和力的测量，而不会影响自然的皮肤感觉。
