Beijing Institute of Nanoenergy and Nanosystems: Triboelectric Nanogenerator Harvests Environmental Energy for Self-Powered VO₂ Phase Transition

Research Background The modulation of transition metal oxides (TMO) properties has significant application value in fields such as smart dimming, thermal insulation, and temperature sensing. Vanadium dioxide (VO₂) is a typical metal-insulator transition (MIT) material, which undergoes significant changes in its structural, electrical, and optical properties during the phase transition. Traditional phase transition modulation methods … Read more

Battery-Free NB-IoT and LoRa: New Opportunities for LPWAN!

Author: Zhao Xiaofei IoT Think Tank Original Introduction With the further development of environmental energy harvesting technology, passive IoT technology can not only provide energy sources for backscatter communication nodes that require only microwatt-level power consumption, but also support NB-IoT, LoRa, and other low-power wide-area network (LPWAN) terminals in certain scenarios, allowing previously battery-dependent nodes … Read more
