3D Printed Materials Based Triboelectric Device for Energy Harvesting and Sensing

Energy harvesting and sensing triboelectric module based on 3D-printed materials have been developed. Rapid prototyping, 3D-printing method is used to prepare sheets of triboelectric materials and simple film casting technique is employed to deposit electrically conductive carbon based elastomeric composite on these dielectrics. The device exhibits capability to detect and harvest energy from mechanical deformation. The developed 3D printed triboelectric system, under tapping condition, provides the maximum rms power of 41.2 μW for the optimum load resistance of 6.1 MΩ that corresponds to the power density of 10.6 μW/cm2. The processing set the building-block towards fully printed triboelectric devices.
