Description
Technical field
The application relates to a kind of sensor, particularly a kind of acceleration sensing device.
Background technology
Existing acceleration transducer is counted step sensor especially and is adopted spring, little hammer and piezoelectric patches to form, inspected object is when doing acceleration movement, hand hammer subband spring of moving acts on piezoelectric patches, produce pressure change on piezoelectric patches surface, export certain deformation signal by piezoelectric patches, processed by circuit, owing to connecting little hammer and piezoelectric patches with spring, easily cause damage to piezoelectric patches, its two complex technical process, also easily damages piezoelectric patches in process.
Summary of the invention
The object of the application is to provide the acceleration transducer that a kind of technique is good, reliability is high.
The object of the application realizes like this, a kind of acceleration sensing device, it is characterized in that: at least comprise a flexible substrate, there is straingauge on flexible substrate surface, gravity body is had on straingauge surface, flexible substrate, straingauge and gravity body are fixed in housing, the cavity body dynamic mobile of gravity body in housing, the outside extraction electrode of straingauge.
Described gravity body is ball, the cavity body dynamic mobile of ball in housing.
Described gravity body is metal barred body.
The beneficial effect of the application: the application owing to having flexible substrate, straingauge and gravity body in housing, by the cavity body dynamic mobile of gravity body in housing, straingauge is subject to gravity body effect, the resistance value of straingauge changes, to be changed situation according to resistance value by treatment circuit, provide output signal.It is simple that it has structural good, processing technology, and cost is low, the advantage of good reliability.
