“…For many sources of mechanical energy (e.g. a car), the energy harvesting system is exposed to physical shocks, vibration and thermal fluctuations (Kubba & Jiang, 2014;Renaud et al, 2014;Zuo & Tang, 2013). So, the components of the harvesting system need to be shock resistant and temperature invariant.…”

This paper presents the design of a rotary motion controller based on the peritrochoid geometry of the rotary (Wankle) engine. It uses an orifice limited flow of incompressible fluid between the chambers of the Wankle-type geometry to control the rotation of the rotor. The paper develops the theory of operation and then implements the design as a Matlab model to simulate the motion control under various conditions. It is found that the time to reach stabilised motion is determined by the orifice size and fluid density. When stabilised motion is achieved, the motion dependence on material and geometry factors is determined by the orifice flow equation. The angular velocity is also found to have a square root dependence on the applied torque when in the stabilised regime. Subjects: Mechanical Engineering; Mechanical Engineering Design; Technology

“…Piezoelectric material generates electrical charge as a result of the applied mechanical force or deformation. The PEH in tire application is divided into two categories depending on how the wasted energy is being used: (a) the vibration energy (flexure and rectilinear) and (2) the strain‐based energy (tire bending and shock loads). The vibration‐based technology that uses a piezoelectric cantilever beam and a tip mass as a mass‐spring system is one of the well‐known configurations.…”

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.

“…This work was further progressed by the same group towards the development of a harvester-powered wireless sensor under noisy conditions generating 28.9 W ac power across a matched load for a TPMS application [2]. However, though subsequent work demonstrated MEMS harvesters delivering sufficient DC power (10's W) for automotive applications, concerns around reliability under high shock and vibration have remained [3]. In other related work, Fan et al [4] and Tang et al [5] previously demonstrated wireless temperature sensor systems powered by miniaturized PVEHs; however, the PVEHs are excited at their natural frequency and at low excitation levels.…”

Despite recent advances in MEMS vibration energy harvesting and ultra-low power wireless sensors, designing a wireless sensor system entirely powered by a single MEMS device under noisy base excitation has remained a challenge. This paper presents a wireless sensor system co-integrated with a single MEMS piezoelectric vibration energy harvester chip excited by band-limited large amplitude noisy vibration characteristic of an automotive application. The use of soft stoppers in the MEMS package enables the harvesters to operate at an excitation level of 10 g(rms). A custom thick AlN (Aluminum Nitride) piezoelectric process is employed to fabricate the MEMS harvesters with a single MEMS chip generating 179 μW rectified power under these excitation conditions. A low-power wireless sensor module and a receiver module were also designed and demonstrated in this work. Experiments show that the wireless sensor module can be powered solely by the MEMS energy harvester commencing from the cold state. Successful wireless data transmission and receival of sensor data packets are recorded under representative conditions.
