“…[84][85][86][87][88][89] Moreover, considering the sustainability of energy consumption during the device's operation, a self-powered flexible monitoring system will be realized if both mechanical and light energies generated from the human body or natural environment can be transformed into the energy required to drive the PPG sensor. [90][91][92][93][94][95][96][97][98][99][100][101] According, the collection and transformation of green energy is of great research significance from the perspective of environmental friendliness and energy conservation. [102][103][104][105][106][107] There is a certain demand for the development of flexible triboelectric nanogenerators with high conversion efficiency which can be effectively integrated with optoelectronic devices and flexible solar cells based on the photovoltaic effect.…”

“…These different responses can be understood by thorough investigation of different body parts which has been discussed thoroughly in this study. The output signal of TUHMD is directly related to the force of impact which controls the amplitude and signal pattern (Abdullah, Flores, et al., 2020; Aminullah, Kasi, Kasi, & Uddin, 2020). Highly sensitive TUHMD has demonstrated different responses due to numerous tiny actions by vocal cord and body muscles which resulted in larger responses.…”

“…The maximum peak‐to‐peak voltage was observed to be 7.4 V for 2.5mm air gap, while the minimum was 2.5 V for 1mm air gap. As the air gap increases, the velocity of impact also increases with constant load frequency which results in contact between the triboelectric layers at higher kinetic energy (Aminullah et al., 2020). Larger amount of electron transfers from paper layer to the PTFE/PDMS layer due to this higher kinetic energy (Abdullah, Flores, et al., 2020).…”

Triboelectric nanogenerators (TENGs) are clean self-powering devices that efficiently convert mechanical energy to electrical energy (Wang, Yang, & Wang, 2017). Since mechanical energy is already present in human activity, these nanogenerators bioharvest such a 'wasted' energy and convert it into useful energy. In this way, TENGs become self-powering motion sensors (Abdullah, Chowdhury, et al., 2020; Yang et al., 2018; Zhang et al., 2019). TENGs are cost-effective, flexible, lightweight, highly sensitive to motion and non-toxic (Wang et al., 2017). These features have attracted the attention of the research development industry, and of professionals interested in collecting real-time body movement. Moreover, the compact size of the TENG permits it to be integrated into assorted wearable items.

“…It is still a challenge to develop triboelectric force sensors with both high sensitivity and a broad detection range.Efforts have been devoted to improving the sensing performances of triboelectric force sensors. Micro-or nanostructured materials, such as cubes, pyramids, [15] domes, [16] and nanowires [17] were introduced into the devices to enhance the sensitivity. High sensitivity can also be obtained by hybridized device structures like combinations of both piezoelectric and triboelectric nanogenerators or electromagnetic and triboelectric generators in one device.…”

In this study, a novel triboelectric device is developed that consists of a silicone‐coated conductive yarn and a PET film as active substances, and an elastic spacer as a force controller. The silicone‐coated yarn is prepared by applying a thermally curable silicone to conductive yarns using a simple but continuous method. The device made of 20 cm long yarn can generate peak voltage as high as 225 V and current outputs of 2.4 µA. The elastic spacer functions to maintain the yarn and PET film in a separate state when no force is loaded and to adjust the response threshold and detection range by changing the spacer area. In comparison to the triboelectric force‐sensors reported previously, this yarn/film device shows a much larger detection range (24–380 N) and higher flexibility in tuning the detection range. The output voltage‐input force curves of the devices have an R2 value above 0.91, indicating the good linearity between the input force and voltage output. Moreover, a theoretical model is developed to elucidate the influence of the spacer area on the detection range and sensitivity. Such a yarn/film/spacer sensor design may be useful for the development of low‐cost force sensors for various applications.
