Title:
DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/033481
Kind Code:
A1
Abstract:
A detection device (100) detects an elastic wave propagated via air. The detection device (100) is provided with: a plate-shaped first electrode (12) that has a cantilever structure having a fixed end (FX) and a free end (FR), and vibrates by being curved by the elastic wave; and a plate-shaped second electrode (32) that faces the first electrode (12) with a predetermined distance therebetween. The detection device (100) detects the elastic wave on the basis of a change in capacitance between the first electrode (12) and the second electrode (32). An end of the second electrode (32) in a direction from the fixed end (FX) to the free end (FR) is located closer to the fixed end (FX) side than the free end (FR).
