This paper presents an adaptive selfconfigurable rectifier to increase the range of vibration excitation that a piezoelectric energy harvesting power management circuit (PMC) can operate with. The proposed circuit configures itself as a voltage doubler (VD) to increase the low voltage of piezoelectric energy harvesters to meet the minimum operating voltage of the PMC. This allows energy harvesting from low voltage range that is not viable using a full-wave bridge (FB) rectifier. When the piezoelectric voltage increases and causes the voltage amplified by the VD to approach the maximum operating voltage of the PMC, the proposed circuit reconfigures itself to FB rectifier that does not amplify the voltage. This allows operation at a higher voltage range that is restricted by the VD topology. Two different reference voltages each for the VD topology and the FB rectifier topology with low-pass filtering are used to ensure correct switching of the rectifier topology. The proposed control circuit can cold start from a piezoelectric voltage of 1.2 V in the VD topology to amplify the voltage to allow an existing PMC that needs a minimum input voltage higher than 1.2 V to operate while consuming 240-410 nW of power. With the two-reference-voltages control method, 20% more energy can be transferred through the PMC than the one without it.

“…The application of this study is limited because it required multiple (or triple in the wind turbine blade application) redundancies as a reference signal. Chew et al [24] implemented a time-multiplexing operation for alternating dynamic strain sensing and energy harvesting functions at different time slots associated with different energy levels. They used the micro-fiber composite (MFC) as a strain sensor and an energy harvester.…”

This paper presents a new self-powered wireless failure detection method that uses different signal transmission rates from piezoelectric energy harvesters. Reliable signal transmission from a wireless sensor network has been challenging due to the power supply issue, often covered by batteries that need regular replacement. Piezoelectric energy harvesting is an excellent option to power the sensors in a vibrational environment, but the power level is limited by input vibrational energy. In this paper, we introduce a new failure detection strategy that uses multifunctional piezoelectric material for vibration sensing and energy harvesting. That is, when the vibration is stronger and the material strain is higher, piezoelectric material produces higher voltage and power. Different power level from multiple piezoelectric sensors is used for sensing structural failure. We design a simple power management circuit that saves power proportional to the piezoelectric voltage so that the piezoelectric patch with higher strain can transmit more frequent wireless signals (higher transmission rate). To store the piezoelectric power, the circuit is composed of a full-bridge rectifier, a Single Pole Double Throw (SPDT) switch, a comparator with hysteresis, and a wireless transmitter (Zigbee). The failure detection performance is investigated in a case study that monitors screw joint failure in a vibrating plate. Reliabilitybased design optimization is conducted to determine the piezoelectric sensor network in terms of the number and sizes of multiple piezoelectric (PZT) patches. The test results show that the proposed system successfully powers the wireless transmitter using the ultra-low scale of power from the PZT sensors (microwatt) and detect the different combination of screw joint failure in the vibrating plate.

High-resolution electronic interface circuits for transducers with nonlinear capacitive impedance need an operational amplifier, which is stable for a wide range of load capacitance. Such operational amplifier in a conventional design requires a large area for compensation capacitors, increasing costs and limiting applications. In order to address this problem, we present a gain-boosted two-stage operational amplifier, whose frequency response compensation capacitor size is insensitive to the load capacitance and also orders of magnitude smaller compared to the conventional Miller-compensation capacitor that often dominates chip area. By exploiting pole-zero cancellation between a gain-boosting stage and the main amplifier stage, the compensation capacitor of the proposed operational amplifier becomes less dependent of load capacitance, so that it can also operate with a wide range of load capacitance. A prototype operational amplifier designed in 0.13-μm complementary metal–oxide–semiconductor (CMOS) with a 400-fF compensation capacitor occupies 900-μm2 chip area and achieves 0.022–2.78-MHz unity gain bandwidth and over 65∘ phase margin with a load capacitance of 0.1–15 nF. The prototype amplifier consumes 7.6 μW from a single 1.0-V supply. For a given compensation capacitor size and a chip area, the prototype design demonstrates the best reported performance trade-off on unity gain bandwidth, maximum stable load capacitance, and power consumption.
