Measurement of Force by Strain Gauges

Fibre Bragg Sensors Compared with Electrical Strain Gauges for Use in Force Measurement - Prospects and Potentials

− This article deals with the technical properties of fiber Bragg gratings with regard to their use as the strain-sensitive element in force transducers. Electrical strain gages are widely used in modern, precise force transducers. The electrical strain gage provides both outstanding technical properties and cost-effectiveness. Besides the electrical strain gage, the measurement principle of fi...

Measurement of strains in fixed bridges with electronic strain gauges.

Nonlinearity and Hysteresis of Resonant Strain Gauges

Nonlinearity and hysteresis effects of electrostatically activated, voltage driven resonant microbridges have been studied theoretically and experimentally. It is shown, that, in order to avoid vibration instability and hysteresis to occur, the choices of the ax . and d.c. driving voltages and of the quality factor of a resonator, with a given geometry and choice of materials, are limited by a ...

A low cost wireless multi-channel measurement system for strain gauges

This paper describes the development of a wireless measurement system for multiple strain measurements on rotational structures. Impulse to this development has been given by an industrial need to measure strains on complex loaded rotating cylinders. After an introduction into the basics of strain measurements and signal conditioning, the principles of the low cost, wireless microphone system a...

Direct Force Measurement of Liposomes by Atomic Force Microscopy

Liposomes serve as models for cells and show increasing applications in medical and nonmedical fields. Unilamellar vesicles are prepared from multilamellar vesicle (MLV) dispersions either by sonication or extrusion. The shape stability of liposomes is important in the understanding of membrane fusion, as well as in drug delivery and gene therapy. Therefore it has been the subject of numerous t...
