Ultrathin Si resonator for gas sensing

Nano-scale mechanical resonator devices have emerged as promising candidates for constructing ultrasensitive sensors capable of detecting mass, force, and charge, among other variables. Our primary objective is to harness this exceptional mass sensitivity to develop state-of-the-art gas sensors. With their compact size, low power consumption, and compatibility with smartphone ecosystems, NEMS resonator devices have the potential to revolutionize portable gas sensors, enabling early detection of specific metabolic diseases. Additionally, our research will investigate the unique fundamental dynamic behaviors exhibited by these devices to further our understanding and enhance their capabilities.
