Special Issue Information

Dear Colleagues,

In today’s world with high population growth, energy is one of the key factors affecting our quality of life and the sustainable development of modern society. At present, the demand for energy is increasing worldwide, and the continuous consumption of non-renewable energy sources leads to ecological degradation and even seriously affects human life and health. In response to the increasing consumption of limited traditional fossil fuel energy on the Earth, the search for sustainable energy sources with reduced carbon emissions and the study of green sustainable energy sources and energy storage technologies are urgent needs for the sustainable development of human civilization. Therefore, in this context, researchers are focused on achieving these requirements by exploring and developing advanced, sustainable, green, nano- and micro-scale novel materials for sustainable ecosystems as well as sustainable health monitoring processes.

The editorial team welcomes the submission of original research articles, reviews, or perspectives from diverse research backgrounds on current research interests in the field of new materials development or the integration of various processes using micro/nanodevice fabrication in sustainable energy development. Micro/nanodevice fabrication may include triboelectric nanogenerators or piezoelectric nanogenerators and their sensors, as well as renewable energy conversion devices. Welcomed topics include but are not limited to sustainable human body mechanical energy storage, sustainable human body mechanical energy sensing, triboelectric nanogenerators for sustainable energy applications, triboelectric nanogenerator fabrication for recyclable materials, and sustainable health monitoring.

The rapid development of wearable electronic devices (such as in applications for health care monitoring, intelligent sports, and human–computer interaction) has led to a huge demand for sustainable energy. However, the existing equipment cannot meet the requirements of energy harvesting, wearable sensing, and environmental protection concurrently. Herein, by an environmentally friendly in situ gap-generation method and doping technology, we have manufactured an Ecoflex–PVDF composite material as a negative triboelectric layer and used gas as a support layer for the triboelectric nanogenerator (EPGS-TENG). The device has excellent electrical output performance and working stability (pressure sensitivity of 7.57 V/N, angle response capacity of 374%, output power of 121 μW, temperature adaptability from 20 °C to 40 °C, durability over 3 h, and stability of 10 days). EPGS-TENG can meet the requirements of biomechanical energy collection and wearable self-powered sensing simultaneously. EPGS-TENG shows great application potential for the new generation of wearable devices. Full article

Gait is the information that can reflect the state index of the human body, and at the same time, the leg is the organ with the maximum output power of the human body. Effective collection of maximum mechanical power output and gait information can play an important role in sustainable energy acquisition and human health monitoring. In this paper, a 3D printing triboelectric nanogenerator (3D printed TENG) is fabricated by 3D printing technology, it is composited of Poly tetra fluoroethylene (PTFE) film, Nylon film, and 3D printing substrate. Based on the principle of friction electrification and electrostatic induction, it can be used as the equipment for human sustainable mechanical energy collection and gait monitoring. In order to solve the problems of energy collection, gait monitoring, and immersion experience, we conducted the following experiments. Firstly, the problem of sustainable energy recovery and reuse of the human body was solved. Three-dimensionally printed TENG was used to collect human mechanical energy and convert it into electric energy. The capacitor of 2 μF can be charged to 1.92 V in 20 s. Therefore, 3D printed TENG can be used as a miniature sustainable power supply for microelectronic devices. Then, the gait monitoring software is used to monitor human gait, including the number of steps, the frequency of steps, and the establishment of a personal gait password. This gait password can only identify a specific individual through machine learning. Through remote wireless transmission means, remote real-time information monitoring can be achieved. Finally, we use the Internet of Things to control virtual games through electrical signals and achieve the effect of human–computer interaction. The peak search algorithm is mainly used to detect the extreme points whose amplitude is greater than a certain threshold and the distance is more than 0.1 s. Therefore, this study proposed a 3D printed TENG method to collect human mechanical energy, monitor gait information, and then conduct human–computer interaction, which opened up a multi-dimensional channel for human energy and information interaction.
