论文摘要
我们提出了一个综合电路，能够从手指接触电容的重复变化中清除能量。对此ASIC的手指敲击会产生大约770pf的电容更换。这些变化进出了电荷泵电路，该电路电路将320pj的能量存储在1NF存储电容器上。我们提出了证明运行的测量结果和模拟。作为概念验证，我们还证明了收获的能量可以为环振荡器供电，该振荡器输出一系列频率，频率从80Hz到30kHz，作为存储电容器电荷和放电。
We present an integrated circuit capable of scavenging energy from repetitive changes in finger touch capacitance. A finger tapping on this ASIC generates a capacitive change of approximately 770pF. These changes feed into a charge-pump circuit which stores 320pJ of energy on a 1nF storage capacitor. We present measurement results and simulations that demonstrate operation. As a proof-of-concept, we also demonstrate that the harvested energy can power a ring oscillator which outputs a series of chirps with frequencies ranging from 80Hz to 30kHz as the storage capacitor voltage charges and discharges.
