The surface flashover phenomena of insulating materials in vacuum greatly weakens the overall performance of vacuum-dielectric system. The improvement of surface flashover characteristics of insulators in vacuum becomes a significant challenge for the development of high voltage electrical equipment. In this paper, we propose a convenient avenue to achieve the high surface flashover performance of...
The low and stable contact impedance between the dry electrode and skin interfaces is crucial for the acquisition of high quality biopotential signal, especially for long-term recording. Building upon this fact, poly(3,4-ethylenedioxythiophene) (PEDOT), was introduced onto the surface of dry electrode to increase the active contact area and reduce contact impedance. Silicon-based dry electrode (6...
Capacitive humidity sensors were fabricated using countersunk interdigitated electrodes coated with amorphous nanostructured TiO2, SiO2, and Al2O3 thin films grown by glancing angle deposition. The capacitive response and response times for each sensor were measured. The sensor utilizing TiO2 exhibited the largest change in capacitance, increasing exponentially from ~ 1 nF to ~ 1muF for an increase...
