Wireless autonomous sensor systems become steadily standard components in our environment and they become smaller, cheaper and more sophisticated. Energy harvesters fabricated by micro-system technology can realize the autonomy of those systems. An overview of latest results and remaining challenges will be given with the focus on vibration energy harvesters. These harvesters are of specific interest where vibrations or repetitive shocks are present. In this paper the application focus will be on tire pressure monitoring systems (TPMS) and ‘intelligent tire’ application. The design and characterization of piezo-electric energy harvesters for this application will be presented together with system optimization of wireless sensor systems mounted in the tire.

Design and Simulation of Model for Energy Harvesting from Vehicle Tires Using Piezoelectric Modules
Piezoelectric materials hold the unique feature of development of electric potential upon application of mechanical stress and vice versa technically known as direct and indirect effect respectively. Many developments in the field of vibration-based energy harvesting in past few decades has been done and the accelerated depletion rate of conventional sources of energy in the recent years has drawn attention of science community towards sustainable energy development and researchers towards development of new energy harvesting techniques to tap the energy lost to the environment. This paper proposes a new design to harvest energy from vehicle tires by the use of PZT modules in the tire carcass utilizing the stresses developed at the tube and tire interface. The design has been modelled in MATLAB Simscape and simulated using COMSOL Multiphysics 5.0. The output voltage can be used to charge batteries for energy storage for future use.

viXra, 2018
Ambient energy harvesting using piezoelectric transducers is becoming popular to provide power for small microelectronics devices. The deflection of tires during rotation is an example of the source of energy for electric power generation. This generated power can be used to feed tire selfpowering sensors for bicycles, cars, trucks, and airplanes. The aim of this study is to optimize the energy efficiency of a rainbow shape piezoelectric transducer mounted on the inner layer of a pneumatic tire for providing enough power for microelectronics devices required to monitor tires. For this aim a rainbow shape piezoelectric transducer is adjusted with the tire dimensions and excited based on the car speed and strain. The geometry and load resistance effects of the piezoelectric transducer is optimized using Multiphysics modeling and finite element analysis.
Tire strain piezoelectric energy harvesters: a systematic review
International Journal of Power Electronics and Drive Systems (IJPEDS), 2021
Intelligent tires are regular tires with additional sensors attached to measure different parameters, such as pressure, temperature, and tire dynamic condition. Sensors mounted inside tires are usually powered by batteries. An alternative power source for these sensors is piezoelectric energy, which uses piezoelectric patches that can be mounted close to the sensors inside vehicle tires. Piezoelectric energy is a battery-less energy source with a long lifespan and environmentally friendly characteristics. This paper presents a comprehensive review of piezoelectric energy harvesters that harvest vehicle tire strain and convert it to electrical energy to power inner tire sensors. The aim of this review was to characterize the possible available tire piezoelectric strain energy harvesters and their advantages and challenges for each type, shape, and material used by researchers so far. The related articles were categorized according to the installation method of the harvester inside the vehicle tire. The four categories are inner tire treadwall, tire bead–rim interface, tire inner sidewall, and tire bead. The maximum power generated was 2300 mW from a treadwall tire strain piezoelectric harvester. Ten challenges were mentioned and classified into three main groups: host environment, installation method, and scavenging system.
A POTENTIAL STUDY OF PIEZOELECTRIC ENERGY HARVESTING IN CAR VIBRATION
Micro Generating System Using Piezoelectric for Low Energy System is a system that provides the user with free flowing energy that can be used without any consequences to the environment. This system enables users to generate low energy for their uses by transforming the mechanical energy produced by the car engine vibration into electrical energy. This project is generally about designing and developing the circuit and its charging system for piezoelectricity. The electrical energy harvested is then charged the capacitor after passing through full wave rectifier. The harvesting system is made up of piezoelectric cantilever that will convert vibration to electrical energy and the charging system is made up of capacitor and known as capacitor banks. The system is then installed at a car engine to generate energy from the car vibration when the engine is switched on. The energy is then being directly used or stored in the capacitor bank for future uses.
Self-powered piezoelectric energy harvester for bicycle
Various electronic accessories, such as on-board computers, communication devices, and wireless sensor nodes, have been installed on bicycles for several years. A powering scheme from ambient energy could avoid the use of batteries and improve the availability of these devices even when the bicycle is unused for a long time. This paper reports on vibration resources detected in a bicycle as a potential energy source for supplying these on-board devices. Measurements showed that the bandwidth of energy vibration is reduced with speed and that the vibrations at any location in the bicycle are nevertheless sufficient for useful vibration harvesting. For this application, a piezoelectric vibration harvester was designed and equipped with a voltage switching interface circuit. Sufficient energy is harvested during the field test.

Simulation of a Novel Bridge MEMS-PZT Energy Harvester for Tire Pressure System
Journal of Physics: Conference Series, 2014
Self-powering is becoming an important issue for autonomous sensor systems. By having an on-the-go power source the life span increases in comparison to a limited battery source. In this paper, simulation of an innovative design for a piezoelectric energy harvester for Tire Pressure Measurement System (TPMS) is presented. The MEMS-based thin-film PZT harvester structure is in the form of a bridge with a big central seismic mass and multiple electrodes. This design takes the advantage of the S-profile bending and a short beam length to concentrate the piezoelectric effect in a small segment along the beam and maximize the power output for a given displacement. From simulation in Comsol Multiphysics, the 9mm x 5mm bridge, seismic mass of 8.7mg and resonance frequency of 615Hz, generates 1 µW by mechanical pulses excitation equivalent to driving at 60 km/h (roughly 180G).
