Recently, 11 experts in the fields of electronic information, biomedicine, new materials and intelligent manufacturing were evaluated in the second Shenzhen excellent scientific and technological academic papers selection activity sponsored by Shenzhen Association for Science and Technology and undertaken by Shenzhen Artificial Intelligence Association. The papers of two 2019 graduates in our group: Wang Yayong, with ” Stretchable Temperature-Responsive Multimodal Neuromorphic Electronic Skin with Spontaneous Synaptic Plasticity Recovery ” and Huang Youchao, with “Flexible Liquid-Based Continuous Direct-Current Tribovoltaic Generators Enable Self-Powered Multi-Modal “Sensing” won the 2nd Shenzhen Outstanding Scientific and Technological Academic Paper Award.

Wang Yarong’s research results proposed and realized the stretchable temperature responsive multi-mode neuromorphic electronic skin based on carbon nanotube channel and electrode, and based on PVA dielectric layer. The array can simultaneously or independently modulate neuromorphic properties through temperature and tensile deformation, and integrates sensing, recognition, storage, self-healing and other functions. The STRM-NES enables efficient, highly sensitive, long-term monitoring and memory of changes in temperature or stress, and real-time in-situ monitoring of individual and external environment information. In addition, the STRM-NES has excellent self-healing capabilities and reusability, showing similar perception, transmission, memory, and self-healing properties to human skin, opening up new possibilities for future applications such as wearable electronic devices, intelligent robots, and skin prosthetics repair.

Huang Youchao’s research proposed and realized a flexible DC friction volt generator with metal – liquid – semiconductor stack structure. This work reports that generators with platinum-water-indium-gallium zinc oxide (IGZO) structures can provide peak short-circuit current density, peak open-circuit voltage, and high power density. Based on density functional theory, the contact characteristics of different solid-liquid interfaces are studied on the atomic scale. It is revealed that the charge transfer between solid and liquid is the key factor affecting the device output. The generator proposed in this work can maintain excellent performance even after more than 50,000 vibration cycles or 30 days of exposure to environmental conditions, showing extraordinary stability. In addition to charging capacitors or driving light-emitting diodes, the device has been further demonstrated for use in self-powered multimode sensing, enabling multifunctional detection of pressure, position and posture, or temperature. This work provides potential solutions and new possibilities for designing the next generation of self-powered wearable electronic devices.

The 2nd Shenzhen Outstanding Scientific and Technological Academic Paper Award is widely collected by Shenzhen Association for Science and Technology (hereinafter referred to as the Association) for universities, research institutes, new research institutions, science and technology enterprises and science and technology workers in Shenzhen with high academic influence in different professional fields. Forums, salons and seminars will be held to discuss the latest progress and development trend in the fields of new generation information technology, life health and new materials, as well as their application in the high-tech industry, and famous domestic experts and scholars will be invited to give speeches around the current academic frontier, to promote academic exchanges in natural sciences and strengthen personnel training. We are committed to building this event into an academic exchange platform with extensive influence.
