“…The metal–PTFE–metal structure is fabricated on an etched PET film, consisting of pressure and temperature sensing parts. The pressure sensing is achieved based on the triboelectric effect of the PTFE film. − The Cu layer deposited on the etched PET surface acts as the bottom electrode, while the Cu pad on the PTFE film is used as the top electrode. Similar to the triboelectric nanogenerator, a potential is created under pressure stimuli due to the charge transfer between PTFE film and substrate that exhibit opposite tribo-polarity .…”

Mimicking human’s tactile sensory capabilities enables the functionality of electronic skin (e-skin), which plays a crucial role in the interaction between humans and the environment, and operation life and stability are key factors for the application. Here, we present the development of passive e-skin with a layered structure to realize tactile capabilities. No external energy supply is required during the achievement of the tactile functions. The fabricated e-skin shows high sensitivity responses with pressure and temperature stimuli simultaneously. Discrimination of surface textures and mimicking humans’ thermosensation are demonstrated by the measurements of time-dependent voltage variations and theoretical fittings. The multifunctional tactile sensing e-skin with low energy consumption provides opportunities of flexible electronics in promising important applications in robotic skins, prosthetics, and wearable sensors.

“…For instance, higher energy conversion efficiencies can be obtained by combining PENG and TENG devices within the same textile structure [92]. Energy harvesting systems may also comprise a storage unit [156]. They may have a dual use as a strain sensor [88] or a motion sensor [73] in the case of piezoelectric systems, or as a haptic sensor [117] or a motion sensor [116] in the case of triboelectric systems.…”

A major challenge with current wearable electronics and e-textiles, including sensors, is power supply. As an alternative to batteries, energy can be harvested from various sources using garments or other textile products as a substrate. Four different energy-harvesting mechanisms relevant to smart textiles are described in this review. Photovoltaic energy harvesting technologies relevant to textile applications include the use of high efficiency flexible inorganic films, printable organic films, dye-sensitized solar cells, and photovoltaic fibers and filaments. In terms of piezoelectric systems, this article covers polymers, composites/nanocomposites, and piezoelectric nanogenerators. The latest developments for textile triboelectric energy harvesting comprise films/coatings, fibers/textiles, and triboelectric nanogenerators. Finally, thermoelectric energy harvesting applied to textiles can rely on inorganic and organic thermoelectric modules. The article ends with perspectives on the current challenges and possible strategies for further progress.

“…Polydimethylsiloxane (PDMS) as an elastic, transparent, and hydrophobic polymer with outstanding electronegativity, which imparts high water resistance and long‐term stability to the TENG, has been researched and used in kinds of TENGs. [ 27–29 ] However, it is not a very efficient triboelectric material, and PDMS worked alone is not appropriate for preparing high‐performance TENG. Therefore, many methods have been studied to modify PDMS for enhancing the power generation of PDMS‐based TENG.…”

Triboelectric nanogenerators (TENGs) are widely used in self‐powered electronic devices and tactile sensors. Herein, for the first time, the facile, low‐cost, and universal electroless deposition (ELD) technology is used to fabricate nonconductive black Cu to enhance the electrical output performance and sensitivities of TENG‐based tactile sensor. The output performance and sensitivities of the equipment are significantly improved by the introduction of black Cu nanoparticles (NPs) coated cellulose filter paper (CFP) into the polydimethylsiloxane (PDMS) matrix. With an optimal load of black Cu NPs, the composite film‐based TENG produces the highest surface charge density exhibited by high sensitivities of 1.56 V N−1, 3.5 times of that obtained via PDMS‐based TENG under the same conditions. These properties facilitate the developed device to be competent at monitoring a kind of human movements, such as finger touching and bending. The proposed strategy not only demonstrates a promising potential of developing large‐scale practical self‐charging equipment and improving the output performance and sensitivities of TENG based tactile sensors but also provides a new perspective for applications in other fields.
