Piezoelectric acceleration sensor and piezoelectric acceleration sensor device
The Journal of the Acoustical Society of America, 1993ABSTRACT The invention relates to a piezoelectric acceleration sensor and to a piezoelectric acceleration device which use a film piezoelectric element. Specifically, the piezoelectric acceleration sensor and the piezoelectric acceleration sensor device generate relatively large outputs when acceleration occurs along the sensing axis, but ...

Microwave ferrite acceleration sensors
IEEE Transactions on Electron Devices, 1969This paper presents a new and potentially simple method of producing a frequency shift proportional to sensed acceleration in a passive microwave device. Magnetostriction effects in microwave ferrite rods are employed to convert an applied stress (acceleration) to a shift in resonant frequency.

Micromechanical Acceleration Sensor
1990A miniature silicon acceleration sensor has been developed, consisting of a capacitive accelerometer and a electronic system. A seismic mass suspended by thin bars is used as sensing element. Signal conversion is achieved by capacitance measurement to fixed electrodes.

Piezoelectric angular acceleration sensor
IEEE Symposium on Ultrasonics, 2003, 2004This paper deals with a piezoelectric angular acceleration sensor, which might be proposed by us, first, as a new concept of the sensor to detect a rotational motion only. In the first part of this paper are dealt with some concrete constructions of this new concept of angular acceleration sensor, composed of piezoelectric transducers.

Multicomponent acceleration sensor
The Journal of the Acoustical Society of America, 1995A multicomponent acceleration sensor in which the inertial force of a seismic mass effects a variation in an electromagnetic quantity of a plurality of individual transducers. During acceleration, the seismic mass acts in each individual transducer a magnetoelastic measuring layer, the permeability μr of which influences the inductance of a sensor coil.
