Convective thermal accelerometers using screen-printed pyroelectric thick-films

摘要: This paper presents a convective thermal accelerometer based on pyroelectric detection. type of uses central heater to produce an hot air mass acting as seismic mass. Its displacement is consequence the application acceleration, measured by two lateral detectors, in our case detectors. The device screen printing technology for deposition electrodes and active material different substrate materials. One has been fabricated alumina with traditional cermet thick-film other one flexible organic new polymer pastes. describes manufacturing poling process well characterizations elements. A comparison performance both accelerometers finally given.
