Special Issue Information

Dear Colleagues,

As popular precision and robotic devices, compliant mechanisms deliver displacement, force and energy by elastic deformation of the materials. Such mechanisms generate smooth motion without the issues of wear, backlash, friction, clearance and are ease of monolithic manufacturing in contrast to traditional rigid-body mechanisms. Motion transmission is realized by flexure hinges, flexible beams, diaphragms, and other soft materials, etc. Targeting different engineering tasks, compliant mechanisms have been applied extensively in both actuator and sensor scenarios, ranging from macro-scale, to micro-scale and to nano-scale. Exemplary applications include micro electro mechanical systems (MEMS), ultra-precision manufacturing, micro/nano-manipulation, precision automatic assembly, medical instruments, to name a few. Compliant mechanisms can transmit information with much high precision, meanwhile, the structural deformation can easily be extended to 2D/3D, facilitating a sensor to receive and convert high-dimensional information. Traditional applications of compliant mechanisms in sensors include single/multiple degree-of-freedom force sensors, accelerometers, mass calibrators, etc. Recent advances in such areas have made emerging electronic skin, flexible printed circuits, and mechanical metamaterials to enhance the performances of sensors and actuators, with an ultra-high sensitivity. These actuator and senor applications are enabled by the novel design/synthesis, sophisticated analysis and implementation of advanced signal processing strategies of compliant mechanisms.

The main focus of this Special Issue is on the state of the art of compliant mechanisms dedicated to diverse sensor science and engineering fields, with a particular interest in soliciting papers from young researchers. The issue is focused on but not limited to the novel synthesis and design theories, modeling and analyses methods, modern manufacturing techniques and applications of compliant mechanisms that can be utilized to improve sensor performances or to configure new conception of sensors. Data acquisition, processing, and systematic optimization are also of concern in this Special Issue.

A large amount of vibration energy exists in the working environment of tractors. Therefore, the use of vibration energy harvesting technology to convert the vibration energy into electrical energy is a feasible way to supply power to low-power sensor equipment in agricultural machinery. Aiming at the problem in which the internal sensors of traditional tractors require built-in batteries or overlapping cables, this work proposes a broadband piezoelectric vibration energy harvester that could harvest the vibration energy from the tractor exhaust cylinder when the tractor is working. The vibration energy can be converted into electrical energy to power the air pressure sensor device. This experimental investigation shows that the energy harvester is composed of a folded piezoelectric energy harvester and a multi-source input synchronous electronic charge extraction circuit.The circuit has a high power density of 12,398 μW/(mm3·g2). Hence, it can convert vibration energy into a wide frequency range between 90–140 Hz and cause the air pressure sensor to operate. Full article
