Title:
PRESSURE SENSOR
Document Type and Number:
WIPO Patent Application WO/2014/155926
Kind Code:
A1
Abstract:
An antenna (60) having an antenna coil pattern (62) formed therein is disposed in a casing (1). A sensor unit (40) has: a surface acoustic wave detection element in which a first detection electrode (42a) for generating and receiving surface acoustic waves and a first reflector (43a) for reflecting surface acoustic waves are formed on a substrate (41) formed from a piezoelectric material; and a sensor coil pattern (45) that is electrically connected to the first detection electrode (42a) and inductively coupled to the antenna coil pattern (62). The sensor unit (40) is disposed on a pressure receiving unit (30, 130, 140a), and wireless signal transfer occurs between the sensor unit (40) and the antenna unit (60) through inductive coupling.
