“…[ 1 ] However, traditional energy supply devices, such as batteries and capacitors, barely withstand a severe deformation because of their strong rigidity in structures. [ 2 ] Triboelectric nanogenerator (TENG) is a newly developing technology to realize self‐powered sensing and low‐frequency energy harvesting, which possesses great application potentials in flexible and wearable electronic device. [ 3 ] Flexible TENG requires that both the triboelectric and electrode layers are flexible and stretchable.…”

Triboelectric nanogenerators (TENGs) represent an emerging technology in energy harvesting, medical treatment, and information technology. Flexible, portable, and self-powered electronic devices based on TENGs are much desired, whereas the complex preparation processes and high cost of traditional flexible electrodes hinder their practical applications. Here, an MXene/polyvinyl alcohol (PVA) hydrogel TENG (MH-TENG) is presented with simple fabrication, high output performance, and versatile applications. The doping of MXene nanosheets promotes the crosslinking of the PVA hydrogel and improves the stretchability of the composite hydrogel. The MXene nanosheets also form microchannels on surfaces, which not only enhances the conductivity of the hydrogel by improving the transport of ions but also generates an extra triboelectric output via a streaming vibration potential mechanism. The measured open-circuit voltage of the MH-TENG reaches up to 230 V even in a single-electrode mode. The MH-TENG can be stretched up to 200% of the original length and demonstrates a monotonical increasing relationship between the stretchable length and the short-circuit voltage. By utilizing the MH-TENG's outstanding stretchable property and ultrahigh sensitivity to mechanical stimuli, applications in wearable movement monitoring, high-precision written stroke recognition, and low-frequency mechanical energy harvesting are demonstrated.

“…196 Likewise, borophene can even function as a supercapacitor with relevant attributes empowering potential portable tools. 197 By adjusting the potential on X-ray tubes, tuneable power can be used to produce X-rays via borophenebased devices for better diagnostics. In perspective, the flexible nature in the absence of a twist can change the molecular arrangement of borophene that can be exploited for the development of wearable strips.…”
