摘要
本文提出了一种无电池的非接触式温度测量系统，该系统由人类有意行为的能量收集提供动力。人的动作和电能之间的转换是由手曲柄电磁转换器提供的。电磁变换器产生的交流电压具有时变幅度和时变频率，并由基于金属氧化物半导体场效应晶体管的倍压有源整流电路进行整流。通过创新的存储电容器顺序充电技术，收集的能量被有效地存储在多个电容器中，并用于为带有相关信号调理电子设备的微机电系统热电堆传感器提供动力，外加一个液晶显示器，以显示温度读数。当对EM转换器施加约29.4 N / 2 cm的力时，电源管理电路能够提取27.5 mJ的能量，并为非接触式温度测量系统供电约33 s。
Battery-less non-contact temperature measurement system powered by energy harvesting from intentional human action
This paper presents a battery-less non-contact temperature measurement system powered by energy harvesting from intentional human action. The conversion between the human action and electrical energy is provided by a hand-crank electromagnetic (EM) converter. The AC voltage generated by the EM converter has time-varying amplitude and frequency and is rectified by a metal–oxide-semiconductor field-effect transistor-based voltage doubler active rectifier circuit. The harvested energy is efficiently stored into multiple capacitors by the innovative sequential charging of storage capacitors technique, and used to power a micro electro mechanical system thermopile sensor with related signal conditioning electronics plus a liquid-crystal display to visualise the temperature readings. With a force of about 29.4 N over 2 cm applied to the EM converter, the power management circuit is able to extract an energy of 27.5 mJ and power the non-contact temperature measurement system for about 33 s.
