International Journal of Latest Trends in Engineering and Technology, 2019

This paper includes development of the model for piezoelectric energy harvesting system using hydro-dynamism and conversion of the dynamic pressure of water into electrical energy. In this article, a model has been designed to harvest energy by using dynamic pressure of water on a single patch of PVDF (Polyvinylidene fluoride), a piezoelectric material. The flowing water is made to strike on a piezoelectric patch of PVDF for the conversion of kinetic/pressure energy of water into electric potential on the basis of piezo-electric effect.

Energy harvesting from fluid flow using piezoelectrics: A critical review

Renewable Energy, 2019

The ambient energy as an available and harvestable energy source which has a high potential to generate electricity for powering electronics devices. Piezoelectric materials, as one of the wellknown energy harvesting mechanisms, play a significant role in converting ambient energy into electrical energy, particularly in small electronic devices such as measuring devices in remote or hostile environments where batteries are not an acceptable option. For this reason, piezoelectric energy harvester (PEH) can help to optimize the weight of structures. In addition, PEH can produce an output voltage in response to the inputs such as thermal, electrical, mechanical and electromagnetic energies. This paper provides a holistic review of the energy harvesting techniques from fluid flow using piezoelectric materials. To this end, the recently conducted research studies in the context of energy harvesting based on the fluid flow motion have been reviewed, considering various modeling and methods for improving the PEH efficiency. Various types of energy harvesting mechanisms, based on vibration by using piezoelectric, have been investigated to identify their opportunities and challenges.

An impacting energy harvester through piezoelectric device for oscillating water flow

2013

The reduced power requirements of miniaturized electronics offers the opportunity to create devices having their power supply based on energy harvesters. In this paper a new idea is proposed and studied to supply underwater low-consumption devices using low-cost disk piezoelectric elements. The system scavenges energy from water motion induced in depth by surface gravity waves using piezoelectric materials and the characteristic oscillating movement of bodies with positive buoyancy that are attached to the seabed with flexible cords, similar to an inverted pendulum. The piezoelectric components that are subjected to impacts produced by the movement of the pendulum create an electrical power generator that harvests the mechanical energy brought by the sea movements. A prototype with the proposed electronic harvesting system is built and tested. The average power output of the prototype is 2.2 ± 0.3 µW, which can be increased signi?cantly with further optimization.

EXPERIMENTAL INVESTIGATIONS OF PIEZOELECTRIC ENERGY HARVESTING WITH TURBULENT FLOW

Agreeing to the Piezoelectric Energy Harvesting Forecast by IDTechEx, the development of the piezoelectric industry is reckoned from 145millionin2018to145 million in 2018 to 145millionin2018to667 million in 2022. This clearly indicates the escalation of interest of the renewable energy market in piezoelectric since its discovery in 1880. Inspired by the growing demand and unique ability of a piezoelectric energy to convert mechanical energy into electrical energy, the authors present an efficient model of a piezoelectric energy harvester in this technical paper. The proposed harvester is capable of producing electricity by converting dynamic fluid flow pressure of waste water into electrical energy using piezoelectric patches made from PZT (Lead Zirconate Titanate). The patches are attached inside the pipes via a mesh and utilizes the flow of segregated waste water flow from households, factories, etc. to produce feasible electricity to power small scale electronic devices. The authors have established the feasibility studies, system engineering experimentations and gathered experimental results confirming the idea and motivation to fabricate and test the actual product.

ADVANCED POWER GENERATION USING PIEZO-SENSOR

Electrical power is the rate at which electrical energy is converted to another form, such as motion, heat, or electromagnetic field. Usage of power turns to be necessity for every work in today's world. To make our daily routines comfortable, the electronic devices are used in large numbers. To generate voltage from footsteps or vehicles the piezo sensors are mounted below the platform. To generate maximum output voltage the sensors are placed in seriesparallel arrangement. This is then given to our monitoring circuitry. The circuit is the micro-controller based circuit that displays output voltage on Liquid Crystal Display. Also, it consists of a USB port where a user can connect cables to charge his/her cell phone. The current is then distributed using (radio-frequency identification) RFID cards so that only an authorized person can access to the system. Thus, we charge a battery using power generated from the footsteps and is display it on LCD using a micro-controller circuit and allow for mobile charging. Major components of our system are Piezo-Sensors, micro-controller ATMEGA328P, LCD and RFID tags.
