Locating a Smartphone’s Accelerometer
The Physics Teacher, 2016While prior papers in this column addressed aspects of radial acceleration using smartphones, this paper describes a technique to locate the accelerometer in the phone to within a couple millimeters.

IEEE Transactions on Power Apparatus and Systems, 1963
A direct measurement of shaft angular acceleration may be made with a conventional drag cup tachometer operated as an accelerometer. In this operating mode the tachometer is supplied with direct current and provides a direct voltage proportional to acceleration.

Surface micromachined accelerometers
IEEE Journal of Solid-State Circuits, 1996Surface micromachining has enabled the cofabrication of thin-film micromechanical structures and CMOS or bipolar/MOS integrated circuits. Using linear, single-axis accelerometers as a motivating example, this paper discusses the fundamental mechanical as well as the electronic noise floors for representative capacitive position-sensing interface ...

Proceedings of the fourth ACM conference on Wireless network security, 2011
Accelerometers are versatile sensors that are nearly ubiquitous. They are available on a wide variety of devices and are particularly common on those that are mobile or have wireless capabilities. Accelerometers are applicable in a number of settings and circumstances, including important security and privacy domains.

In-fiber integrated accelerometer
Optics Letters, 2011A compact in-fiber integrated fiber-optic Michelson interferometer based accelerometer is proposed and investigated. In the system, the sensing element consists of a twin-core fiber acting as a bending simple supported beam. By demodulating the optical phase shift, we obtain that the acceleration is proportional to the force applied on the central ...

A 2D micromachined accelerometer
Proceedings of Third International Conference on Electronics, Circuits, and Systems, 2002A surface micromachined 2-D accelerometer is designed and implemented in CMOS. The implementation requires the addition of three masking steps to a commercially available standard CMOS process. It has a /spl plusmn/100 g full range reading and better than 1% linearity within this range with a sensitivity of 0.5 mV/g.

A Novel Recording Accelerometer
Review of Scientific Instruments, 1949The novel features of a small recording accelerometer of slow chart speed are described. Principally, these are its compactness—the recorder, less power supply, fits into a panel type aircraft instrument case—and the use of spark recording to obtain a visible record on a paper chart.
