We proposed electrostatic motor that new actuator microrobot in our previous research. used waveform generator generate driving waveform. In this paper, will propose using chip. cell body model basic component outputs 3 MHz frequency electrical oscillated pul...

This work shows zero-power shock sensing for the combination of a micro-triboelectric generator and MEMS electrostatic actuator system where mechanical to causes it produce voltage, this voltage is used actuate Micro-Electro-Mechanical-system (MEMS) switch. For first time, we present fabrication process Triboelectric-Nano-Generator (TENG) with technology. The MEMS-TENG has suspended 1.5 mm × pl...

A new type of single-phase stand-alone induction generator using a three-phase induction machine and a single-phase voltage-source PWM inverter is introduced. The generator scheme is capable of producing constant load frequency with a very well regulated output voltage. A small lead acid battery and a single-phase full diode-bridge rectifier are used to feed the inverter. The inverter feeds one...

in this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3d finite element modeling and experimental tests. the structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...

a quantum chemical investigation was carried out to study the properties of intermolecular f•••f, br•••br and br•••o interactions in crystalline 1-bromo-2,3,5,6-tetrafluoro-nitrobenzene (bfnb). this system was selected to mimic the halogen-halogen as well as halogen bonding interactions found within crystal structures as well as within biological systems. we found that fluorine atoms have weak ...

Energy harvesting is a new promising research area for portable electronics. Portable electronic devices have been typically limited by the finite lifetime and size of the internal batteries. This has been a constant conflict and tradeoff between battery size and device capabilities. For instance, cardiac pacemaker lifespan is mostly limited by battery size, which occupies at least half the ava...

This paper reviews kinetic energy harvesting as a potential localised power supply for wireless applications. Harvesting devices are typically implemented as resonant devices of which the power output depends upon the size of the inertial mass, the frequency and amplitude of the driving vibrations, the maximum available mass displacement and the damping. Three transduction mechanisms are curren...

The Bakken Library and Museum announces the availability of a new online database of its outstanding collection of artifacts relating to the history of electricity and magnetism and their uses in medicine and the life sciences. Records for approximately 90 per cent of The Bakken’s unique collection of roughly 2,000 artifacts have been entered into the database along with images of almost every ...

in this article our objective is to obtain steady state characteristics of shunt, series, and separately excited dc motors coupled with a centrifugal water pump supplied through a step-up, step-down, and cuk converter from photovoltaic generator. we assume that there are no storage batteries and, of course, the system must operate on maximum utilization i.e. maximum water must be pumped. it is ...

In a series of comprehensive studies, a wide range of air cleaning methods has been evaluated related to their effectiveness in removing radon decay products. Data show that while filtration and electrostatic precipitation were effective in reducing total potential alpha energy concentrations (PAECs), they caused a greater percentage of the radon decay products, subsequently formed, to be unatt...
