Wearable sensors continually evolve to become more epidermal‐like, yet still face challenges pertaining to conformability and reliance on wires and power sources. Herein, a nontoxic silver conductive ink made from children's school glue is used as a versatile medium for rapid, on‐demand wearable sensor development. This conductive ink can be painted directly onto the skin and to achieve dry electronics with maximal skin contact suitable for electrocardiogram use. Multilayer pressure sensors and near‐field communication (NFC) resonators manufactured using the silver ink demonstrate wireless and battery‐free capabilities for physiological monitoring purposes.

用于按需传感器和电路的涂装表皮电子设备

可穿戴式传感器不断发展，变得越来越像表皮，但仍然面临着与一致性和对电线和电源的依赖有关的挑战。在本文中，由儿童学校用胶制成的无毒银导电油墨被用作通用介质，可快速按需开发可穿戴传感器。可以将这种导电墨水直接涂在皮肤上，并获得干燥的电子设备，使皮肤接触最大化，适合心电图检查。使用银墨水制造的多层压力传感器和近场通信（NFC）谐振器展示了用于生理监测目的的无线和无电池功能。
