Transparent, Stretchable, and Adhesive Conductive Ionic Hydrogel-Based Self-Powered Sensors for Smart Elderly Care Systems

“…In recent years, there has been a growing interest in wearable electronic devices, which are increasingly used in the fields of the Internet of Things, artificial intelligence, robotic haptics, and smart elderly care systems. − Usually, electronic device systems are mostly made of rigid synthetic polymer materials, which are not suitable for wearable devices. − There is a great need to develop the next generation of flexible wearable electronic devices that are soft, stretchable to accommodate body movements and preferably self-powered to avoid the use of bulky batteries and cumbersome charging steps. − Conductive gel polymers, including ionic liquid (IL) gel, ionic hydrogel, and organic hydrogel, are chemically or physically cross-linked three-dimensional polymer networks containing conductive materials and free-moving ions. − With tunable mechanical properties and conductivity, these soft gels have been extensively investigated to develop soft and stretchable triboelectric nanogenerator (TENG)-based self-powered sensors and integrate them into wearable human–machine interaction (HMI) devices. , …”

Ultrastretchable Triboelectric Nanogenerators Based on Ecoflex/Porous Carbon for Self‐Powered Gesture Recognition

“…[20][21][22] It is a promising candidate for self-powered energy system because of flexibility, [23] highoutput power density, [24] abundant material source, [25] and easy integration. [26] Currently, TENG has made remarkable breakthroughs through different methods including work modes, [27][28][29][30] materials modification, [31,32] and structure design. [33][34][35] Especially, stretchable TENG (STENG) has become the research hotspots in flexible power supply.…”

Harsh Environmental-Tolerant and High-Performance Triboelectric Nanogenerator Based on Nanofiber/Microsphere Hybrid Membranes

“…At the same time, the Chinese Ministry of Science and Technology, China’s Ministry of Education, and the Chinese Academy of Science issued by “Nanotechnology” key special also explicitly proposed the use of energy conversion and storage in the nano-materials technology, nano energy and environmental technology as the key development direction and research task, strive to resolve environmental load, low energy efficiency, resource bottlenecks and other major common problems, and committed to the development of a series of environmental protection, low energy consumption, renewable green energy technology. From these, it is particularly important to explore new ways of harvesting energy, which has also received close attention in recent years [ 12 ]. There are various forms of mechanical energy in the daily environment, such as human motion energy, wind energy, water wave energy, etc., which have an abundance of reserves and come from a wide range of sources [ 13 , 14 ].…”
