A novel force transducer for the measurement of grip force

Journal of Biomechanics, 2001
A new strain gauge transducer has been developed to measure functional grip forces. The gripping area is a cylinder of diameter 30 mm and length 150 mm and simulates the handle of a number of devices, allowing a range of activities to be studied. The device measures radial forces divided into six components and forces of up to 250 N per segment can be ...

Cellular force measurement for force reflected biomanipulation

IEEE International Conference on Robotics and Automation, 2004. Proceedings. ICRA '04. 2004, 2004
In biological cell manipulations, manual thrust or a skilled operator, relying only on the visual feedback information only, usually performs penetration of injection pipette into single cells. Accurately measuring cellular force is a requirement for minimally invasive cell injection and it is essential in investigating biomechanical properties of cell

Force perception measurements at the foot

2004 IEEE International Conference on Systems, Man and Cybernetics (IEEE Cat. No.04CH37583), 2005
The goal of this study is to determine the effect of amplitude and frequency of force sinusoids on force perception of the foot, in order to design an effective haptic feedback system for gas pedals. Eight subjects were asked to push a gas pedal to a constant workpoint position against a background force of 25 N.

Concept of a Force-Measuring Horseshoe

Cells Tissues Organs, 1993
To further develop objective methods in the field of gait analysis a force-measuring horseshoe (FM shoe) has been developed. The ground reaction forces were determined by measuring the degree of displacement between the two solid parts of the shoe. This was done by three removable measuring units (MUs) that were equipped with strain gauges and placed ...

A Forceps to Measure Strabismus Forces

Archives of Ophthalmology, 1972
A forceps modified on the scheme of a torquewrench is described. The instrument allows quantitative assessment of the normal resistance and of abnormal restrictions which confront the eye muscles as they rotate the eye. The instrument also allows quantitative assessment of the active muscle force available for the task.

Force measurements in screw fixation

Journal of Biomechanics, 1976
Abstract An entire range of screw sizes and types from one manufacturer (Synthes, Switzerland) along with two experimental sizes were tested in bovine cancellous bone to measure torque of insertion, screwdriver pressure, axial compression generated by the screw, screw breaking strength and efficacy of various head types.

The hydrophobic force: measurements and methods

Phys. Chem. Chem. Phys., 2014
The hydrophobic force describes the attraction between water-hating molecules (and surfaces) that draws them together, causing aggregation, phase separation, protein folding and many other inherent physical phenomena.

Force Measurements for Cancer Cells

2017
During cytoskeleton remodeling, cancer cells generate force at the plasma membrane that originates from chemical motors (e.g., actin). This force (pN) and its time course reflect the on and off-rates of the motors. We describe the design and calibration of a force-measuring device (i.e., optical tweezers) that is used to monitor this force and its time

Bridge measurement of electromagnetic forces

Electrical Engineering, 1935
A simple impedance bridge may be used to measure the variation of inductance of a disconnecting switch of practical dimensions as the switch blade is displaced by slight amounts from the closed position. The electromagnetic force tending to open the switch blade, calculated from the observed variation of inductance, checks the theoretical value ...

Comparison of measures of forced expiration

Journal of Applied Physiology, 1977
Theoretical relationships among a number of parameters were derived for idealized timed vital capacity (TVC) and maximal expiratory flow-volume (MEFV) curves to determine a minimal set of independent parameters. Normal pediatric subjects and those with cystic fibrosis were studied to verify these relationships experimentally. The average flow over the
