Title:
WIRELESS TYPE MEASUREMENT APPARATUS USING SURFACE ACOUSTIC WAVE-BASED MICRO SENSOR AND METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/036460
Kind Code:
A2
Abstract:
Disclosed are a wireless type measurement apparatus using a Surface Acoustic Wave (SAW)-based micro sensor and a method thereof. The wireless type measurement apparatus using the SAW-based micro sensor according to one embodiment of the present invention includes: a SAW-based micro sensor which converts a wirelessly received pulse signal to a SAW, generates a plurality of pulse signals by reflecting the converted SAW to measure a change of environmental elements, and wirelessly transmits the pulse signals; and a reader which generates the pulse signals to measure the change of the environmental elements, wirelessly transmits the pulse signals to the SAW-based micro sensor, generates the pulse signals whenever an interval between the plurality of pulse signals received through the reflection of the transmitted pulse signals with respect to the SAW micro sensor corresponds to an interval between the pulse signals of the set environmental elements, wirelessly transmits the generated pulse signals to the SAW-based micro sensor, and measures the change of the environmental elements by counting the generated pulse signals during a predetermined time.
