For the purpose of utilizing decomposition component analysis (DCA) for fault diagnosis of SF6 gas insulated equipment further, SF6 spark decomposition experiments under different spark energies were carried out on the frequency and energy-controllable SF6 spark decomposition test platform. The amount of gaseous by-products of SF6 sparks were measured by GC-MS. The main gaseous by-products of SF6...
We report guidelines for symmetric threshold voltage (Vth) in double gate (DG) tunnel FinFETs (tFinFETs) with single and dual metal gate electrodes. To realize the symmetric Vth=±0.2V, the work function difference (ΔΦm) of each gate electrode in n- and p-type tFinFETs with a nondoped Si channel must be 1.34 eV, indicating that tuning the effective work functions in the dual metal gates is difficult...
Epilepsy affects approximately one percent of the world population. Antiepileptic drugs are ineffective in approximately 30% of patients and have side effects. We are developing a noninvasive, or minimally invasive, transcranial focal electrical stimulation (TFS) system through our novel concentric ring electrodes to control seizures. Here we report on the development of a seizure detecting algorithm...
Semitransparent flexible resistive-switching memory devices, using amorphous InGaZnO as the switching layer, are fabricated on plastic substrates at room temperature. The device shows high performance, excellent flexibility, and mechanical endurance in bending tests. No performance degradation occurs, and the stored information is not lost after bending the device to different angles and up to ...
There are millions of people in the U.S. and many more worldwide who could benefit from a noninvasive-based electroencephalography (EEG) brain computer interface (BCI). A BCI is an alternative or augmentative communication method for people with severe motor disabilities. However, EEG suffers from poor spatial resolution and signal-to-noise ratio (SNR). To improve the spatial resolution and SNR many...
We present the integration of super long horizontally aligned single-walled carbon nanotubes (SWNTs) on the micromachined wide trenches for infrared (IR) sensor application. The HA-SWNTs were found to be able to grow across trenches as wide as 1000 mum forming parallel SWNT bridges on the trench. The sensor fabricated with only one process shows sharp and remarkable responses to the ~ 4 mW IR radiations...
Summary form only given. Corona discharge can improve the distribution of voltage between the switch gaps as well as provide initial electrons which benefit the discharging process when the switch is fired1'Icirc1. To investigate the effects of the corona discharge, a single gap switch with toroidal electrodes is designed. Corona discharge occurs on the tips of the needles when the gap is charged...
Electroencephalography (EEG) has high temporal resolution, but lacks high spatial resolution even after increasing the number of electrodes. Although EEG is intended to record cerebral activity, it also records electrical activities arising from sites other than the brain, artifacts. To remove major artifacts like electrooculogram (EOG), electrocardiogram (EMG) and ECG present in EEG, many techniques...
The strength and conductivity of carbon nanotubes make them attractive materials for incorporation into composite materials for use in electrically lossy structures. Applications could include light-weight structures that are absorptive of radio and microwave signals. We have derivatised multi-walled nanotubes by acid treatment, formed them into layers on resistor-like chips, and then subjected these...
Partial discharge (PD) measurements in air, argon and helium, under pressures from 101.3 kPa (760 Torr) down to 0.27 kPa (2 Torr), have been performed for both 60 Hz AC and DC energization. The electrode arrangement is a twisted pair of insulated conductors taken from a standard aircraft wiring harness. The paper describes the physical PD test setup, the electrical connections for AC energization,...
