Performance analysis of lateral sliding mode triboelectric nanogenerators for self-powered healthcare applications

Abstract

In the sphere of healthcare, self-powered sensing and energy collection have been revolutionized by triboelectric nanogenerators. The integration of small-scale energy devices has resulted in significant enhancements to health and quality of life in implanted biomedical electronics. This article specifically addresses planar lateral sliding mode triboelectric nanogenerators. The output performance of an lateral sliding mode can be affected by factors such as the dielectric layer thickness, electrode thickness, dielectric constant, surface area, surface charge density, weight of the structure and other environmental factors. This study analyzes the intrinsic electrical output of the lateral sliding mode, such as the open-circuit voltage, capacitance, short-circuit charge, energy, efficiency and stability with biocompatibility. The results showed that triboelectric nanogenerators with thin dielectric films exhibit higher voltage, charge, and energy than those with thicker dielectric materials. Additionally, the performance of the triboelectric nanogenerators was influenced by maintaining a constant positive layer thickness and varying the negative layer thickness. Moreover, different electronegative films in triboelectric nanogenerators based on dielectric constants produced the best electrical output during relative dielectric constant testing. The lateral sliding mode modeling and simulations were performed using MATLAB software, which was used for the design, material selection, and stationary study of healthcare devices. This work provides a practical framework for utilizing the triboelectric effect in various healthcare equipment to generate energy from low-vibration human movement. The biocompatibility, light weight, and small size of triboelectric nanogenerators make it a promising technology for enhancing life and health in the future.
