“…For example, as indicated, a maximum power of 0.4 mW can only be achieved from mechanical vibrations occurring in tires due to tire-road contact by a FR4-based electromagnetic energy harvester (Hatipoglua and Urey, 2009). Also, a power density of only 1.37 lW/mm 3 can be generated by a piezoelectric composite energy harvester of 31 model attached to the inner liner of the tire (Lee et al 2012), which is much less the power density of 107.9 lW/mm 3 generated by the new harvester in this work. In addition to the fact that the piezoelectric technology has higher transduction efficiency than that by the electro-magnetic technology, a piezoelectric ring harvester can fully harvest the energy induced by the tires of vehicles by its 33 mode.…”

“…The fabricated device generated a peak power of 288 lW and an average power of 5.8 lW from an input acceleration of 9.8 m/s 2 at 10 Hz. Lee, Kimi, Oh, and Choi (2012) presented a piezoelectric composite energy harvester attached to the inner of a tire to transfer the longitudinal tire strain into the electric power. The harvester (60 Â 10 Â 0.3 mm) can generate a power density of 1.37 lW/mm 3 to supply a wireless sensor.…”

“…The effect of the vehicle speed and tire inflation pressure may be also considered on the tire strain. It is reported that by increasing the tire rolling speed from 8 to 26 rpm, the longitudinal strain increases slightly about 9% and the vehicle speed does not affect the tire strain significantly, thus the effect of velocity is assumed to be negligible in this study. Although by decreasing the tire inflation pressure the strain is increased but the rate of strain change by the effect of load and speed is almost independent of the inflation pressure, therefore, it is assumed that the tire is used on the manufacturer recommended pressure.…”

“…Therefore, the required energy for a sensor to measure 1000 samples per revolution in each axis and transmit 840 bits in each revolution (35 bytes per axis) would be 8.7 μJ/rev. In a typical commercial tire monitoring system (tire pressure monitoring system [TPMS]), the average energy needed is assumed to be about 10 μJ/rev . To reduce the amount of energy that a TPMS uses, certain programming is required so that the system will transmit signals only once a faulty pressure or temperature is detected by the system.…”

Summary Basic parameters affecting vehicle safety and performance such as pressure, temperature, friction coefficient, and contact‐patch dimensions are measured in intelligent tires via sensors that require electric power for operation and wireless communication to be synchronized to the vehicle monitoring and control system. Piezoelectric energy harvesters (PEHs) can extract a fraction of energy that is wasted as a result of deflection during rolling of tires, and this extracted energy can be used to power up sensors embedded in intelligent tires. A new design of PEH inspired from Cymbal PEHs is introduced, and its performance is evaluated in this paper. Cymbal PEHs are proven to be useful in vibration energy harvesting, and in this paper, for the first time, the modified shape of Cymbal energy harvester is used as strain‐based energy harvester for the tire application. The shape of the harvester is adjusted in a way that it can be safely embedded on the inner surface of tires. In addition to the high performance, ease of manufacturing is another advantage of this new design. A multiphysics model is developed and validated to determine the output voltage, power, and energy of the designed PEH. The modeling results indicated that the maximum output voltage, the maximum electric power, and the accumulated harvested energy are about 3.5 V, 2.8 mW, and 24 mJ/rev, respectively, which are sufficient to power two sensors. In addition, the possibility is shown to supply power to five sensors by increase in piezoelectric material thickness. The effect of rolling tire temperature on the performance of the proposed PEH is also studied.

At present, the most convenient and effective method for ensuring air pressure inside automobile tires being kept in normal state is using a tire pressure monitoring system to monitor the tire's interior pressure and temperature in real time. Aiming at the power supply problem of direct tire pressure monitoring system in automobile industry commonly, a new giant magnetostrictive vibration-power generation technology which generates electricity through collecting vibration energy in automobile is proposed. Based on the coupling effect of inverse magnetostrictive effect and Faraday electromagnetic effect, a power generation device prototype which uses giant magnetostrictive material as the core element is developed. It may be a prototype of giant magnetostrictive vibration-power generation module used to provide electricity to tire pressure monitoring system instead of button battery power supply mode. In order to accurately describe the relationship between vibration force (stress) and output voltage in the giant magnetostrictive vibration-power generation process, a mathematical model is established from the essence of inverse magnetostrictive effect. According to energy conversion process generated in the process of power generation using giant magnetostrictive material, the modeling process is divided into two parts. Moreover, in order to derive the energy conversion efficiency of giant magnetostrictive vibration-power generation device, a computing method of power generation efficiency is proposed. Experiment results show that the model can accurately describe the relationship between vibration force (stress) and output voltage. Amplitude of the output voltage generated by giant magnetostrictive vibration-power generator is proportional to the amplitude or frequency of vibration force approximately. For the giant magnetostrictive vibration-power generation prototype developed in this paper, its energy conversion efficiency reaches 32.6%. Research result provides an effective method for solving the power supply issue of tire pressure monitoring system. It plays a certain promoting role for the realization of battery-less tire pressure monitoring system.
