AI Article Synopsis
- The study showcases the use of gold nanoparticle membranes as sensors to detect ambient pressure changes through electromechanical signal transduction.
- The sensors are made by sealing microstructured cavities with membranes created from cross-linked gold nanoparticles, which are connected to metal electrodes on either side.
- Changes in external pressure cause the membranes to bend, increasing the distance between nanoparticles, allowing for easy detection of these changes by measuring the resistance of the membranes.
Article Abstract
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.
