摩擦纳米发电机（TENG）是实现可穿戴电子器件自供电的一种很有前途的电源。然而，由于其脉冲输出，需要电源管理电路，如间歇操作电路和AC-DC转换器，来驱动电子设备。在这项研究中，我们提出了一个简单而高效的由可编程单结晶体管组成的间歇操作电路。从存储电容到负载的能量传递效率达到89%。我们证明了间歇性电路可以用来驱动电子设备，如秒表和手表，使用基于碳纳米管的可拉伸TENG产生的电力。
Triboelectric nanogenerator (TENG) is a promising power source toward the realization of self-powered wearable electronics. However, because of its pulsed output, a power management circuit, such as an intermittent operation circuit and AC–DC converter, is required to drive electronic devices. In this study, we propose a simple and highly efficient intermittent operation circuit composed of a programmable unijunction transistor. The energy transfer efficiency from the storage capacitor to the load reached 89%. We demonstrated that the intermittent circuit can be used to drive electronic devices such as stopwatches and wristwatches using the electricity generated by a carbon-nanotube-based stretchable TENG.
