Recently, the Robotics and MEMS (Micro-Electro-Mechanical Systems) technology group led by Professor He Guangping from the School of Mechanical and Materials Engineering of North China University of Technology has made significant progress in flexible nano-energy collection/sensor research. His research paper "Flexible Semitransparent Energy Harvester with High Pressure Sensitivity and Power Density Based on Laterally Aligned PZT Single-Crystal Nanowires was published in the internationally renowned journal ACS Applied Materials & Interfaces (IF: 7.504, SCI District TOP). Associate Professor Zhao Quanliang from the Institute of Mechanical Materials of North China University of Technology is the first author of the research paper. Professor He Guangping and Associate Professor Song Weili of Beijing University of Science and Technology are co-authors. Â The pressure-type flexible nano-energy collector is a flexible micro-electronic device that can be used to convert pressure mechanical energy into electrical energy by using micro-nano processing and nano-material preparation technology, and also has dynamic pressure sensor function. The traditional structure piezoelectric flexible nano energy collector mainly adopts a "sandwich" multilayer film composite structure, and the charge generated by the nano piezoelectric material in the middle layer is difficult to reach the upper and lower electrodes through the low dielectric constant insulating polymer around it. Layers tend to result in lower output current density and power density. Â He Guangping's group used hydrothermal method to synthesize lead zirconate titanate (PZT) piezoelectric single crystal nanowires, and combined with MEMS micromachining technology, designed and fabricated a flexible nano energy collector with PZT nanowire lateral distribution structure. Among them, the PZT nanowire is in direct contact with the parallel interdigital electrode, so that the piezoelectric charge generated by the pressure can be directly reached and outputted directly to the electrode layer. The experimental results show that the device's pressure sensitivity and DC power output performance are improved by about 2 orders of magnitude and 2.7 times, respectively, compared with the conventional structure piezoelectric flexible nano-energy collector, and the device also has visible-near-infrared light translucency and Better pressure sensing linearity, can be widely used in environmental energy harvesting power generation, smart electronic skin, flexible touch screen sensing display, portable / wearable electronic devices.
