中暑是一种严重的疾病，每年可能会伤害许多受害者。许多智能物理传感器已被开发出来，以防止中暑死亡。然而，它仍然是一个挑战，以制造皮肤粘附，小，低成本的传感器，在现场中暑检测，以克服物理传感器的弱点。据我们所知，这是开发基于PDMS的独立式纳米片皮肤贴片的第一个突破，该贴片由pH传感元件（锑/氧化锑和银/银碘酸盐）组成，以实现高pH敏感性和可重复性。传感元件的结构和形态特性进行了研究。易于使用和易于制造的纳米片传感器表现出-43 mV/pH的线性pH响应。总体而言，所开发的传感器显示出高灵敏度、可重复性和稳定性。我们的初步结果表明，开发的传感器粘附良好的皮肤表面。预计这种概念验证方法与其他物理传感器不同，可以提供可靠的制造和测量。
Heatstroke is a serious illness that can potentially damage many victims every year. Many intelligent physical sensors have been developed to prevent heatstroke fatalities. However, it remains a challenge to fabricate skin-adhesive, small, and low-cost sensors for in situ heatstroke detection to overcome the weaknesses of the physical sensors. As far as we know, this is the first breakthrough for exploiting a PDMS based freestanding nanosheet skin patch consisting of pH sensing elements (antimony/antimony oxide and silver/silver iodate) to achieve high pH sensitivity and repeatability. The sensing elements were investigated for structural and morphological properties. The easy to use and easy to fabricate nanosheet sensor exhibited a linear pH response of -43 mV/pH. Overall, the developed sensor showed high sensitivity, repeatability, and stability. Our initial results indicate that the developed sensor adhered well to a skin surface. It is expected that this proof of concept approach gives reliable fabrication and measurement unlike other physical sensors.
