Abstract
ABSTRACT Recently, the application of flexible sensors in mechanical equipment has attracted widespread attention. However, the design of vibration sensor materials and structures for complex mechanical environments still faces challenges. Hence, we proposed an annular structure CCTO/PDMS-based triboelectric nanogenerator (CP-TENG) as self-powered triboelectric automotive bolt tightness sensor. Due to the high dielectric properties of CCTO/PDMS film, the CP-TENG device can obtain high electrical output performance to achieve high sensitivity sensing. Through the annular structure design, CP-TENG devices can be integrated into bolt fittings with good structural compatibility. The output voltage and current of CP-TENG can monitor the different accelerations borne by the bolts from 9 to 60 m/s2. Moreover, by installing on the gasket, the CP-TENG device can also monitor bolt looseness to achieve early warning of the safety status of automotive components. This research can promote the development of self-powered sensor in the field of automotive bolt vibration monitoring.
期刊介绍：
Materials Technology: Advanced Performance Materials provides an international medium for the communication of progress in the field of functional materials (advanced materials in which composition, structure and surface are functionalised to confer specific, applications-oriented properties). The focus is on materials for biomedical, electronic, photonic and energy applications. Contributions should address the physical, chemical, or engineering sciences that underpin the design and application of these materials. The scientific and engineering aspects may include processing and structural characterisation from the micro- to nanoscale to achieve specific functionality.
