Wearable Human Motion Monitoring Using Vertical Contact Separation Mode Triboelectric Nanogenerator

Abstract

Wearable human motion monitoringhas become an integral part of the paradigm shift that is on the horizon in the field of healthcare for a wide variety of biomedical applications. In recent years, there has been incessant advancement in smart wearable technology capable of human motion monitoring ranging from strain sensors to piezoelectrics. This paper proposes to fabricate a Triboelectric Nanogenerator based on Vertical Contact Separation (VCS) mode with design characteristics offlexibility, low cost, simple and easy to fabricate design for real - time monitoring of human body movements. The output performance of fabricated VCS - TENG is analysed by finger tapping. In order to conduct human motion monitoring, VCS - TENG is affixed on different body parts, and the corresponding signal is analysed. The developed prototype can be further integrated with advanced electronics to deliver promising technology in the field of healthcare diagnostics and monitoring.

Unravelling the Ageing Effects of PDMS‐Based Triboelectric Nanogenerators

“…[1] Due to its excellent electronwithdrawing ability, PDMS has been widely adopted as a negative triboelectrification material in triboelectric nanogenerators (TENGs), which are energy transducers that convert oscillatory mechanical motions into electrical power. [2] Applications of PDMS-based TENGs have been explored in a variety of promising fields, such as power generation, [3,4] wearable selfpowered devices and sensors, [5][6][7] Internet of Things, [8] and tactile e-skins for soft robotics. [9][10][11][12] The flexibility, stretchability, and DOI: 10.1002/admi.202400094 mechanical resilience of PDMS elastomers enable its easy adaptation to a myriad of potential TENG applications and composites, while maintaining a reasonably high power output density ranging from ca.…”

“…Over the years, substantial effort has been put into developing strategies to enhance the electrical output of PDMSbased TENGs, including surface texturing, [4,15] surface functionalization, [16] ion injection, [17] and incorporation of fillers. [3,5,12] Such strategies can either induce more charge generation on the surface or add charge traps within the material for better charge storage. [18] However, limited research has been focused on the ageing effect of polymeric materials and how this might affect the durability of the TENG devices derived from elastomers such as PDMS.…”

Biophysical Sensors Based on Triboelectric Nanogenerators

“…In recent years, with the increasing demand for health, the design and development of TENG-based wearable biosensors in human health monitoring and personalized medicine have garnered significant attention [ 10 ]. At the same time, biomechanical energy is one of the most used energy sources.…”

A multimodal PDMS triboelectric nanogenerator sensor based on anodised aluminium oxide template preparation for object recognition

“…[1][2][3] TENGs usually have four different modes: single electrode mode, lateral sliding mode, independent mode and vertical contact separation mode. [4][5][6] Currently, TENGs have broad applications ranging from energy harvesting [7][8][9][10][11][12] to human-computer interaction [13][14][15][16] and physiological monitoring, [17][18][19] and they are attracting research interest globally.…”
