Autocalibration of MEMS Accelerometer

2006 IEEE Instrumentation and Measurement Technology Conference Proceedings, 2006
In this paper a new approach of an auto calibration method for micromechanical sensors is proposed. In particular, recalibration of acceleration sensors without any additional laboratory equipment is considered. If the device is stationary, the proposed procedure exploits the fact that the output vector of the acceleration sensor should match the ...

Accelerometer and angular accelerometer

The Journal of the Acoustical Society of America, 1996
An accelerometer includes a main body, a displacing member, a scale, and a detecting unit. The displacing member is attached to the main body and has a displacing portion displaced relative to the main body at least in a direction of acceleration measurement in accordance with a force applied.

Translational accelerometer and accelerometer assembly method

The Journal of the Acoustical Society of America, 1990
An accelerometer comprising a body (10, 16, 12), a proof mass (18, 30, 32), a mounting strucutre comprising flexures (20, 22) for mounting the proof mass to the body, and force sensing elements (34, 38). The flexures permit translational motion of the proof mass with respect to the body along a sensitive axis SA and rotation of the proof mass with ...

A comparison of an implanted accelerometer with a wearable accelerometer for closed-loop DBS

2022 44th Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2022
Sensing technology, as well as cloud communication, is enabling the development of closed-loop deep brain stimulation (DBS) for Parkinson's disease. The accelerometer is a practical sensor that can provide information about the disease/health state of the patient as well as physical activity levels, all of which in the long-term can provide feedback ...

RFID Threshold Accelerometer

IEEE Instrumentation & Measurement Magazine, 2008
This paper presents the design, manufacture, and testing of a battery-free, wireless threshold accelerometer based on a fully compliant bistable mechanism (FCBM). The FCBM stores threshold acceleration measurements mechanically, eliminating the need for electrical power. The sensorpsilas state can be read wirelessly via a passive RFID tag.
