With the development of technology, self-powering devices by harvesting bioenergy is an efficient way to achieve sustainable system operation. In this paper, we fabricated a flexible hybrid nanogenerator (HNG) based on multilayer nanocomposites, innovatively using biocompatible Polylactic acid (PLA) as piezoelectric material and multi-walled carbon nanotubes (MWCNTs) and polydimethylsiloxane (PDMS) as triboelectric material. A simple method was used to prepare the MWCNTs/PDMS films with surface microstructure. By coupling the triboelectric effect and the piezoelectric effect, a 3 cm × 3 cm HNG can generate an output of 80 V and 125 nA under a pressure stimulation of 20 N. Furthermore, due to the good flexibility and biocompatibility of our device, we can use it to harvest human energy.

Nowadays, wearable electronic devices are developing rapidly with the internet of things and human–computer interactions. However, there are problems such as low power, short power supply time, and difficulty in charging, leading to a limited range of practical applications. In this paper, a composite hydrogel composed of polyacrylamide, hydroxypropyl methylcellulose, and MXene (Ti3C2T x ) nanosheets was developed, which formed a stable double-chain structure by hydrogen bonding. The configuration endows the hydrogel with excellent properties, such as high strength, strong stretchability, excellent electrical conductivity, and high strain sensitivity. Based on these characteristics, a flexible multifunctional triboelectric nanogenerator (PHM–TENG) was prepared using the hydrogel as a functional electrode. The nanogenerator can collect biomechanical energy and convert it to 183 V with a maximum power density of 78.3 mW/m2. It is worth noting that PHM–TENG can be applied as a green power source for driving miniature electronics. Also, it can be used as an auto-powered strain sensor that distinguishes letters, enabling monitoring under small strain conditions. This work is anticipated to provide an avenue for the development of new intelligent systems for handwriting recognition.
