Abstract:
Traditional flexible tactile sensors usually have high hysteresis and creep due to the use of viscoelastic materials such as Polydimethylsiloxane, rubber, etc., which brings about the low data accuracy and high unreliability in dynamic and static loading applications. Herein, a capacitive tactile sensor based on airbag-structured electrode (ASE) is proposed, which has low hysteresis and creep. The feasibility of ASE in reducing the hysteresis and creep of sensors is determined by theoretical derivation and finite element analysis and confirmed through experimental data. Based on the ASE, the proposed sensor has low hysteresis of 2.94% and low creep of 3.11%. In addition, the sensor also has key characteristics such as good sensitivity, wide linear sensing range, low detection limit, high durability, and good repeatability. These features enable the sensor to perform well in dynamic and static loading applications and show a promising potential for other applications in human-machine interaction. © 2025 Elsevier B.V.
