Experimental Investigation on Thermoelectric Generator for Battery- Charger Based Oven

In this research paper, thermoelectric generator (TEG) module was embedded inside the oven to harvest electrical energy from heat waste of the kitchen oven.  The development of experimental setup was investigated in closed-circuit from room temperature rise to 150°C in 60 min using kitchen oven with custom-made aluminum heatsink with built-in water-cooling tank attached on the TEG module. The maximum voltage output was generated about 1.87V in single TEG module where gradient of TEG was measured about 0.0337V/°C.  The harvested output of voltage was demonstrated by charging a single lithium battery ‘AA’ in 110 mins for full-charged and it was able to power a LED torch light

An Experimental Investigation Of Piezoelectric P (VDF-TrFE) Thick Film On Flexible Substrate As Energy Harvester

This paper proposes an experimental investigation of energy harvester using poly(vinylidene fluoride-trifluoroethylene) or P(VDF-TrFE) thick-film on flexible substrate by using print screen and rod method. Polyester film being used as the substrate where a sandwiched layer of electrode-piezopolymer-electrode thick film is deposited on. The thick-film is then annealed at 100°C and polarized at 100 V for the film with a thickness of about 18µm, being inspected under EDX, FESEM and XRD. The fabricated energy harvester piezoelectric is able to generate a maximum output power of 4.36 µW at an externa l electrical load of 1 kΩ with a maximum peak-to-peak of about 3.0V when an impact free-fall force of 0.2N was applied on the thick-film

Design and Characterization of Piezoelectric P(VDF-TrFE) Thick Film on Flexible Substrate for Energy Harvesting

This paper discusses on the design and fabrication steps of piezopolymer using poly(vinylidene fluoride) trifluoroethylene, P(VDF-TrFE) thick film on the flexible substrate using screen-printed method. Polyethylene terephthalate, PET film was used as a substrate to hold P(VDFTrFE) thick film in between sandwiched layers of electrodepiezopolymer-electrode. The P(VDF-TrFE) thick film is then annealed at 100 °C and polarized at 100 V for the film and inspected under EDS, FESEM and XRD for the characterization process. The flexible piezoelectric P(VDFTrFE) thick film is able to generate maximum output peak power of 4.36 µW at an external load of 1kΩ with generated maximum peak-to-peak voltage about 3.0 V for energy harvesting applications when using impact force test from freefall drop plasticine of 0.2 N was applied to the thick film

Finite Elements Method Simulation of P(VDF-TrFE) Piezoelectric Sensor for Internet of Things Application

This paper presents finite element method (FEM) simulation and internet of things application by using P(VDF-TrFE) piezoelectric sensor where there are mechanical vibration present on the piezoelectric material for batteryless sensors. Therefore, this simulation was conducted using COMSOL Multiphyisc 5.1 to study the resonance frequency, stress, displacement and load dependence for the P(VDF-TrFE) piezoelectric sensor. The optimized design of P(VDF-TrFE) piezoelectric sensor was tested in the step monitoring application by using the internet of things (IoT) system
