“…The first is typically a diode bridge, whereas the second is a toggling power converter [28][29]. Piezoelectric micropower generators with modified power conversion circuits [30][31][32] include a half-wave synchronous rectifier with a voltage doubler, a full-wave synchronous rectifier, and a passive full-wave rectifier circuit.…”

In piezoelectric energy harvesting systems, energy harvesting circuits are the interface between piezoelectric devices and electrical loads. The conventional view of this interface is based on the concept of impedance matching. In fact, in the power supply circuit can also apply as an electrical boundary conditions, such as voltage and charge, to piezoelectric devices for each energy conversion cycle. The major drawback of piezoelectric power harvesting have low-power relationships in systems within (in the range of μW to mW), then system also have significantly reduced any potential losses in circuits that make up the EH system, whereas other condition into careful selection of circuits and components can enhanced the energy harvesting performance and electricity consumption. In the study of energy harvesting systems, it is an energy harvesting system approach that using active and passive electronic circuit to control voltage and or charge on piezoelectric devices as proposed and review to mechanical inputs for optimized energy conversion. Several factors in the practical limitation of active and passive energy consumption, due to device limitations and the power efficiency of electronic circuits, will be introduced and have played an important role into to enhance optimum and increase efficiency of energy harvesting system.

“…Piezoelectric material is very useful among these wearable devices, which can monitor the added force and generate the electric signal proportional with the force [22]. Most importantly, the electric energy can also be used as the power source to supply the system, showing a possibility to replace the cumbersome battery system [23,24]. With the development of material synthesis technologies, the material can also have more and more functionalities and flexibility [25,26].…”

How to replace the referee in sports with artificial intelligence has attacked a huge amount of attention recently. In this paper, non-battery pressure detection and communication system are designed and fabricated aiming to help the referee in the basketball games. To get the information from player and ball at the same time, the designed system is consisted of three parts, including the basketball monitoring system, the shoes monitoring system, and the laptop to collect and process the data. For the basketball monitoring system, eight piezoelectric polyvinylidene fluoride (PVDF) flexible thin films are used as the sensor on the surface of the basketball with the sensitivity of 0.065 V/N and four hard piezoelectric Lead Zirconium titanite (PZT) patches are set inside the ball as the power source. As for the shoes monitoring system, four PZT patches work as both power source and pressure sensor with a sensitivity of 0.025 V/N. To solve the referee problem in basketball game, time delay of different systems is first measured. The different systems have similar time delay of about 3s, which will help to make sure whether the players break the rules. In this paper, whether the player has a traveling violation in a game can be refereed by the collected data, which has more than 97% accuracy. This work shows an innovative progress in automatic referees in games and the Internet of Things (IoT) in the human health monitoring.
