A flexible acoustic pressure sensor was developed based on the change in electrical resistance of three-dimensional (3D) graphene change under the acoustic waves action. The sensor was constructed by 3D graphene foam (GF) wrapped in flexible polydimethylsiloxane (PDMS). Tuning forks and human physiological tests indicated that the acoustic pressure sensor can sensitively detect the deformation and the acoustic pressure in real time. The results are of significance to the development of graphene-based applications in the field of health monitoring, in vitro diagnostics, advanced therapies, and transient pressure detection.
基于三维（3D）石墨烯在声波作用下电阻的变化，开发了一种柔性声压传感器。该传感器由包裹在柔性聚二甲基硅氧烷（PDMS）中的3D石墨烯泡沫（GF）构成。音叉和人体生理测试表明，该声压传感器能够实时灵敏地检测变形和声压。这些结果对于基于石墨烯的应用在健康监测、体外诊断、先进治疗和瞬态压力检测领域的发展具有重要意义。
