Abstract
Piezoresistive cement-based pressure sensors can detect traffic flow and structural changes in concrete structures. However, their reliance on significant external energy inputs limits practical adoption. This study develops an integrated cement-based device that implies a cement-based triboelectric nanogenerator (TENG) to harvest mechanical energy and power the piezoresistive cement-based sensor through a specially designed circuit, enabling electrical resistance monitoring under external mechanical loads. The device determines the fractional changes of resistivity (FCR) by analysing current changes in two separate branches. The optimized 1.0 wt% graphene nanoplates (GNP) incorporated into cementitious…
