摩擦纳米发电机 TENG

摩擦纳米发电机(TENG)是一种基于摩擦起电和静电感应原理,可将机械能转化为电能的装置,因其高度贴合了健康器件所提出的小型化、自供电、安全性高、舒适美观等要求,近年来得到了越来越多的关注。

Triboelectric nanogenerator (TENG) is a device that can convert mechanical energy into electrical energy based on the principles of frictional electrification and electrostatic induction. It highly meets the requirements of the miniaturization, energy saving, high safety and comfort proposed by health care devices. Thus, TENG has received more and more attention in recent years.

基于悬挂系统的能量收集与减负背包
Power Backpack Based on Load-suspended System for Energy Harvesting and Reduced Load Impact

鉴于野外徒步探险、科考、训练以及救援等需要长途行进的活动中,背负的仪器装备及随身穿戴的电子设备等会使身体产生累计性疲劳,降低人体机能;同时,随身携带的电子产品会受限于电池能量存储与寿命,课题组开发了一套基于悬挂系统的能量收集与减负背包。这种新型的背包利用弹性绳和滑轮组的悬挂系统解耦背负负载和人体的运动,实现减负和缓震;同时,利用摩擦纳米发电机的基本原理即静电感应和摩擦生电产生电能,实现人体走路和跑步等振动能量的收集。背包为解决野外负重徒步行进中的累积性疲劳和电能供给问题,提供了一种可行性解决方案,有很好的科学研究与市场应用前景。

Considering the fact that there is a cumulative fatigue caused by the research equipment and wearable electronics in backpack when taking the outdoor hiking, research exploration and athletic training, etc. This cumulative fatigue will impair the human performance. Moreover, the demanded electricity is limited by the energy storage and lifetime of batteries. Here, a power backpack based on load-suspended system for energy harvesting and reduced load impact is proposed and two elastomers and pulley blocks are incorporated to decouple the synchronous movement of the load and the human body, which realizes the labor-saving and shock absorption. In addition, based on the electrostatic induction and triboelectrification effects as the primary principle of triboelectric nanogenerator (TENG), it can harvest the vibration energy with continuous electricity in walking and running. This backpack provides a feasible solution for the problems of accumulative fatigue and electricity supply in the wild walking with heavy loads and has great potential for the scientific research and market applications.
