This paper presents a novel readout system for wireless passive pressure sensors based on the inductively coupled inductor and cavity (LC) resonant circuits. The proposed system consists of a reader antenna inductively coupled to the sensor circuit, a readout circuit, and a personal computer (PC) post processing unit. The readout circuit generates a voltage signal representing the sensor’s capacitance...
This article describes a manufacturing method of embedded cavity using zirconia casting-belt and multi-layer lamination technology for the high temperature ceramics, as the present high temperature ceramics are difficult to form a sealed cavity and encapsulation is complicated. Complete the preparation of high temperature ceramics sealed cavity, by using punching machines to punch out the cavity in...
