An Electrostatic Servo Capacitive Pressure Sensor
IEEJ Transactions on Sensors and Micromachines, 1999 We have fabricated an electrostatic servo capacitive pressure sensor by using bulk silicon micromachining and SODIC(SOot-Deposited Integrated Circuit) wafer. The sensor consists of fixed electrodes and two diaphragms which are connected with pillars to move together for electrostatic servo force balancing. It detects pressure by the servo-voltage which

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
