用于医疗保健的附着在皮肤上的柔性电子设备（例如表皮电子设备）必须努力解决生物相容性问题，并适应特定的皮肤环境（如呼吸和排汗）。在这里，我们报告了一种生物相容性柔性温度传感器的策略，其灵感来自于皮肤，通过使用具有多孔结构的半透膜作为基材，具有优异的透气性和高质量的防水性。我们将这种温度传感器安装在腋下和前臂上，分别测量腋窝温度和体表温度。志愿者佩戴这种传感器24小时并洗澡两次，体外测试未显示对皮肤有浸渍或刺激的迹象。特别是，还测量了由流动的空气和水滴引起的皮肤表面的精确温度变化，以验证准确性和动态响应。结果表明，生物相容性温度传感器在人体皮肤上柔软、透气，与水银温度计相比具有优异的精度。这证明了将传感器充分用于医疗用途的长期体温传感以及机器人或假肢的人造皮肤的传感功能的可能性和可行性。
Flexible electronics attached to skin for healthcare, such as epidermal electronics, has to struggle with biocompatibility and adapt to specified environment of skin with respect to breath and perspiration. Here, we report a strategy for biocompatible flexible temperature sensors, inspired by skin, possessing the excellent permeability of air and high quality of water-proof by using semipermeable film with porous structures as substrate. We attach such temperature sensors to underarm and forearm to measure the axillary temperature and body surface temperature respectively. The volunteer wears such sensors for 24 hours with two times of shower and the in vitro test shows no sign of maceration or stimulation to the skin. Especially, precise temperature changes on skin surface caused by flowing air and water dropping are also measured to validate the accuracy and dynamical response. The results show that the biocompatible temperature sensor is soft and breathable on the human skin and has the excellent accuracy compared to mercury thermometer. This demonstrates the possibility and feasibility of fully using the sensors in long term body temperature sensing for medical use as well as sensing function of artificial skin for robots or prosthesis.
