Comprehensive evaluation of the piezoresistive behavior of carbon nanotube-based composite strain sensors

Theoretical analysis of the piezoresistive behavior of carbon nanotube (CNT)-based composites is of great importance for understanding the electro-mechanical response of CNT-based composite strain sensors. In this paper, a comprehensive analytical model is developed to predict the electro-mechanical response of conductive CNT-based composite sensors by considering some critical factors, such as CNT dimensions, interphase, nanotube waviness, and...
