Abstract

As the number of flexible electronic devices grows dramatically, the energy harvesting and storage technology of flexible electronic devices also urgently needs to advance. Traditional flexible electronic devices are battery-powered, which not only suffer from short endurance and large size, but also do not meet the new era requirement of environmental protection and energy saving. Therefore, this study investigates the self-powered system in flexible electronic devices using the Triboelectric Nanogenerator (TENG) technology. The research innovatively optimizes the TENG, proposes a liquid metal triboelectric Nanogenerator (LMTENG), and optimizes the optimal path selection problem. In the test results, the optimal output power of 567.3 μ W is obtained when the contact frequency is 2 Hz for an external load of 15 MΩ. By comparing with the current TENG, the LMTENG significantly improves the optimal output power. On the other hand, the LMTENG is able to respond to a pressure of 22 kPa and maintain normal performance at 50% stretching. The study provides new ideas for improvement of triboelectric nanogenerators and also contributes to the optimization of flexible electronic devices.

柔性电子器件中自供电系统的改进摩擦电纳米发电机
随着柔性电子器件数量的急剧增长,柔性电子器件的能量收集和存储技术也亟待发展。传统的柔性电子设备采用电池供电,不仅续航时间短、体积大,而且不符合环保节能的新时代要求。因此,本研究利用摩擦纳米发电机(TENG)技术研究柔性电子器件中的自供电系统。本研究创新性地优化了摩擦电纳米发电机,提出了一种液态金属摩擦电纳米发电机(LMTENG),并优化了最优路径选择问题。测试结果表明,当接触频率为2 Hz,外部负载为15 MΩ时,输出功率为567.3 μ W。与现有的TENG相比,LMTENG显著提高了最优输出功率。另一方面,LMTENG能够响应22 kPa的压力,并在50%拉伸时保持正常性能。该研究为摩擦电纳米发电机的改进提供了新的思路,也有助于柔性电子器件的优化。
