在本通信中，金纳米粒子膜作为环境压力传感器与机电信号转导的应用程序进行了演示。该装置通过用1，6-己二硫醇交联的金纳米颗粒的膜密封微结构腔来制造，所述膜通过沉积在腔的两侧上的金属电极电接触。外部压力的变化导致膜的偏转，从而增加了平均颗粒间距离。因此，通过简单地监测膜的电阻，可以容易地检测压力变化。
In this communication the application of gold nanoparticle membranes as ambient pressure sensors with electromechanical signal transduction is demonstrated. The devices were fabricated by sealing microstructured cavities with membranes of 1,6-hexanedithiol cross-linked gold nanoparticles, which were electrically contacted by metal electrodes deposited on both sides of the cavities. Variations of the external pressure resulted in a deflection of the membranes and, thus, increased the average interparticle distances. Therefore, the pressure change could easily be detected by simply monitoring the resistance of the membranes.
