We will develop versatile capacitive micromachined ultrasonic transducers (CMUTs) that use a unique Polymer-Graphene, PolyGr, composite developed by our collaborators at the University of Manchester as a device layer (active membrane). CMUTs have a wide range of applications, including pressure sensors, speakers, ultrasound transmitters and receivers, gas sensors, and liquid and chemical sensors. PPolyGr has superior properties compared to the device layers currently used in CMUTs. It is particularly attractive for aquatic applications of CMUTs where the polymer layer can also function as a dielectric to protect against short circuits in ionized liquids.

我们将开发多功能电容式微机械超声换能器（CMUT），该换能器使用由我们在曼彻斯特大学的合作者开发的独特的聚合物-石墨烯，PolyGr复合材料作为设备层（活性膜）。CMUT具有广泛的应用，包括压力传感器、扬声器、超声波发射器和接收器、气体传感器以及液体和化学传感器。与CMUT中当前使用的器件层相比，PPolyGr具有优越的上级性能。这对于CMUT的水生应用特别有吸引力，其中聚合物层还可以用作电介质以防止电离液体中的短路。
