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.

用于中暑检测的先进的基于皮肤的人工电子pH传感系统。

中暑是一种严重的疾病，每年可能会伤害许多受害者。已经开发了许多智能物理传感器来防止中暑致死。然而，制造用于现场中暑检测的具有皮肤粘性的，小型且低成本的传感器仍然是一个挑战，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剂的第一个突破，该贴剂由pH感测元件（锑/氧化锑和银/碘酸银）组成，以实现高pH敏感性和可重复性。研究了传感元件的结构和形态特性。易于使用且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，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，开发的传感器可以很好地粘附在皮肤表面。可以预期，这种概念验证方法可提供与其他物理传感器不同的可靠制造和测量。
