Vibrational energy harvesting by means of piezoelectric transducers has been of particular interest in recent years for powering autonomous, wireless devices. In this context, a non-linear treatment of piezoelectric voltage greatly enhances electromechanical conversion. This paper presents an ultra-low power circuit implementation of the technique called Synchronized Switch Harvesting on Inductor (SSHI). The circuit detects the zero-current condition through the rectifier with a series shunt resistor and a nano-power comparator. Simulations show that the maximum power extracted is approximately 6.7 times greater than with a passive rectifier. The estimated overall consumption of the circuit components is 4 µA. The measured voltage flip efficiency is between 91% and 94%. |
