Vibration energy harvesting is a process by which ambient mechanical from environment or host structures converted into usable (usually, but not always, electrical energy). This technology considered to be relatively new method for supplying sustainable low-powered sensor networks and electronic devices. Various vibration harvesters utilizing piezoelectric, electromagnetic, electrostatic, tribo...

Intelligent tires are regular with additional sensors attached to measure different parameters, such as pressure, temperature, and tire dynamic condition. Sensors mounted inside usually powered by batteries. An alternative power source for these is piezoelectric energy, which uses patches that can be close the vehicle tires. Piezoelectric energy a battery-less long lifespan environmentally frie...

Assessing the remaining value (RV) of agricultural machines is essential to compute depreciation costs, especially in second-hand market, although previous scientific studies have employed scrap as an estimate RV (10 years life). Since Brazil, a developing country, at very first steps process grape harvest mechanization, it likely that harvesters will be mainly imported and for this task. ASABE...

The increasing amount of Internet Things (IoT) devices and wearables require a reliable energy source. Energy harvesting can power these without changing batteries. Three-dimensional printing allows us to manufacture tailored in an easy fast way. This paper presents the development hybrid non-hybrid 3D printed electromagnetic vibration harvesters. Various approaches, their utilised geometry, fu...

We demonstrate the feasibility of using novel, small energy harvesters to power atmospheric sensors and radios simply attached to a single conductor of existing overhead power distribution lines. We demonstrate the ability to harvest the required power for operating multiple atmospheric and power-system sensors, together with short-range radios that could broadcast atmospheric sensor data to th...

In most low-power systems, power management is generally thought of as being an ability to switch certain parts of a system off or put them in a low-power state when they are not required, and to manage the charging of a battery. While these are important aspects of low-power electronics powered by energy harvesters, there are much more fundamental reasons for requiring power electronics in an ...

Wireless Sensor Networks (WSNs) enable many vital applications ranging from environmental monitoring to human health control. Main research efforts in the WSNs focused on minimizing energy consumption because wireless sensor nodes are mostly powered by batteries which are usually hard to replace. Recent research on long-lasting WSNs is proposing energy harvesters combined with rechargeable batt...

Recent progress on high-performance polymer electrets based on CYTOP, novel charging methods using soft X-ray and vacuum UV, and development of MEMS energy harvesters are discussed. With the parylene high-aspect-ratio nonlinear springs and high-performance polymer electrets, we have successfully developed a MEMS electret generator for energy harvesting applications. With an acceleration of 1 G,...
