A piezoelectric … The output voltage from the piezoelectric generator, the output voltage after rectification, and the controlled voltage output are shown in Figure 5(a–c), respectively. The Indian Institute of Technology Mandi (IIT-Mandi) on Monday said its researchers proposed a technique to enhance the power output of piezoelectric materials. Many measuring instruments designed for piezoelectric sensors or measurement microphones have an IEPE constant current source integrated at the input. Piezo amplifiers with an output voltage on the order of 100V to 200V are typical, and higher voltages are not uncommon for larger and more powerful actuators.
