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.

Acceleration and deceleration sensor
The Journal of the Acoustical Society of America, 1987An acceleration and deceleration sensor for use with safety devices in motor vehicles includes a reed switch and a movably mounted permanent magnet system which closes the switch during a collision. The permanent magnet system is provided by a pair of magnets having like poles which face each other, so that the magnets repel each other.

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.

Surface Micromachined Acceleration Sensors
2020Micromechatronic sensors have many applications in measuring linear acceleration along one or several axes. For example, accelerometers are widely applied in cars for detecting crashes and for triggering the release of airbags. In mobile devices, they switch the display between landscape and portrait format.

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.

Acceleration sensor and measurement method
The Journal of the Acoustical Society of America, 1997An acceleration sensor has a seismic mass having movable electrodes. The movable electrodes are designed as differential capacitors between two fixed electrodes. Also provided are additional electrodes which are arranged opposite movable electrodes or opposite bending elements on which the seismic mass is suspended.
