A Modified Algorithm for Reducing Calculation Errors in Large Strain Measurement with Strain Gauges

Measurement of strains in fixed bridges with electronic strain gauges.

Calculation of Long Bone Loading Using Strain Gauges

The standard methodology for measuring loads in long bones is the in situ load cell, which enables direct measurements, but alters the stiffness and mass of the subject bone. Bone loading can also be calculated by applying linear beam theory to measurements from strain gauges affixed to the bone surface. The efficacy of the strain gauge method was assessed in this study by mounting three strain...

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...

A Modified 2D Multiresolution Hybrid Algorithm for Ultrasound Strain Imaging

Ultrasound elastography is an imaging modality to evaluate elastic properties of soft tissue. Recently, 1D quasi-static elastography method has been commercialized by some companies. However, its performance is still limited on high strain level. In order to improve the precision of estimation during high compression, some algorithms have been proposed to expand the 1D window to a 2D window for...

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...
