Manufacturing Graphene and Graphene-based Nanocomposite for Piezoelectric Pressure Sensor Application: A Review

Abstract

Strain sensors have spread at present times, and their electrical resistance has been interpreted. In reality, the use of strain sensors has broadened the reach of technology and allowed us to track changes in the environment in various ways. In recent years, due to their distinctive properties, films based on advanced carbon nanomaterials have started applying sophistication sensing. The strength of the tailored material has been obtained in addition to the various functions applied to these nanomaterials due to the particular structure of the nanomaterials. A prime catalyst for developing nanoscale sensors was this excellent feature. Carbon nanomaterials-based films have been increasing widely due to the excellent properties of nanocomposite-based films for sensing applications (piezoelectric application). There is also an instinctive structure of nanomaterials so that the material is high. Carbon nanomaterials such as graphene are now an excellent alternative for the production of sensors for thermal, electric and mechanical reading.

Nanocarbon-based sensors for the structural health monitoring of smart biocomposites

“…Based on the working mechanism, pressure sensors are generally divided into four categories such as piezo-resistivity, 107 triboelectricity, 108 capacitive, 109 and piezoelectricity. 110 The piezoresistive pressure sensor converts mechanical pressure into resistance change. It has cost-effective synthesis, simple design, scalability, and fast response.…”
