This paper reviews the state-of-the art in vibration energy harvesting for wireless, self-powered microsystems. Vibration-powered generators are typically, although not exclusively, inertial spring and mass systems. The characteristic equations for inertial-based generators are presented, along with the specific damping equations that relate to the three main transduction mechanisms employed to...

We have developed a micro-electro-mechanical systems (MEMS) electrostatic vibratory power generator with over 100 μWRMS of (root-mean-square) output electric power under 0.03 GRMS (G: the acceleration of gravity) accelerations. The device is made of a silicon-on-insulator (SOI) wafer and is fabricated by silicon micromachining technology. An electret built-in potential is given to the device by...

Electrostatic precipitators (ESP) and fabric filters (FF) are the main air pollution control equipment utilized to clean dust laden fumes from utility boilers. The choice among these systems depends on specific site conditions such as dust characteristics, required efficiency, gas flowrate and temperature. ESP are generally characterized by higher capital investments and lower operating charges...

Electrostatic devices generating an electric field (EF) are promising tools for greenhouse tomato cultivation. In these devices, EF is generated in the space surrounding insulated conductor (IC) that charged by a voltage generator. Thus, physical force exerted on any insect enters EF, as negatively IC (NC-IC) pushes negative charge (free electrons) out of body. The polarized positively to be at...

BACKGROUND/AIM We are developing a neutron dynamic therapy (NDT) with boron tracedrugs for a new mechanical-clearance treatment of pathotoxic misfolded, aggregated, and self-propagating prion-associated disease proteins. We present a compact neutron generator-based NDT using a boron tracedrug UTX-51. Our NDT is based on the weak thermal neutron-bombarded destructive action of UTX-51 on bovine s...

The Ball Bearing High Voltage generator is a fairly simple and transparent apparatus that can serve as tool to motivate conceptual descriptions calculations in electrostatics are normally presented our students rather dry matter-of-fact fashion.

Telecommunications providers expect products to perform reliably during operation in the field. Achieving the expected hardware reliability is due to an amalgamation of multiple factors. A significant contribution to reliable performance results from the incorporation of specific materials, which are very corrosion resistant and electrostatic discharge (ESD) safe during the design and manufactu...

This study employs a simple measurement methodology that is based on the de-convolution of a square test stimulus to measure the transmission characteristics of the human body channel in an electrostaticcoupling intra body communication system. A battery-powered square waveform generator was developed to mimic the electrostatic-coupling intra body communication system operating in the environme...

A very good test of the general robustness of a digital product is that of electrostatic discharge immunity (ESD), which is also a common test under the essential requirements of the EMC Directive. The test is specified in IEC 61000-4-2, which includes a standardized pulse generator and a procedure for applying the stress to the equipment under test (EUT). Not only is this method referenced in ...
