AGING COMPENSATION OF A FERROELECTRIC PIEZOELECTRIC SHOCK SENSOR

A method comprises receiving a signal from a piezoelectric device and receiving a measurement of a temperature of the piezoelectric device. The method further comprises reading a first parameter from a memory, in which the first parameter depends on the temperature and relates the signal to an accel...

Beschreibung
Zusammenfassung:	A method comprises receiving a signal from a piezoelectric device and receiving a measurement of a temperature of the piezoelectric device. The method further comprises reading a first parameter from a memory, in which the first parameter depends on the temperature and relates the signal to an acceleration value and reading a second parameter from the memory, in which the second parameter represents a degree of drift of the piezoelectric device at the temperature. The method further comprises determining an acceleration of the piezoelectric device based on the signal, the first parameter, and the second parameter.
