Biomechanical data provide fundamental information about changes in musculoskeletal function during development, adaptation, and disease. To facilitate the study of mouse locomotor biomechanics, we modified a standard mouse running wheel to include a force-sensitive rung capable of measuring the normal and tangential forces applied by individual paws. Force data were collected throughout the ni...

nanoscale science and technology has today mainly focused on the fabrication of nano devices. in this paper, we study the use of lithography process to build the desired nanostructures directly. nanolithography on polymethylmethacrylate (pmma) surface is carried out by using atomic force microscope (afm) equipped with silicon tip, in contact mode. the analysis of the results shows that the dept...

Patients with spasticity were unable to maintain a constant force of the anterior tibial muscle. The force at maximal effort was reduced to less than 40% of normal, partly because motor units fired at a reduced rate even at high levels of contraction. Force and instantaneous frequency fluctuated slowly. The fast regulation of the firing rate, which characterises normal muscle, was absent. The v...

A variable temperature, ultrahigh vacuum atomic force microscope AFM was used to characterize interfacial friction for a single-asperity diamond contact on a diamondlike carbon DLC substrate over a nominal substrate temperature range of 90 to 275 K. Calibrated friction force measurements were obtained by analyzing lateral force hysteresis loops as a function of normal force. For sufficiently la...

This paper presents the design of a computer-controlled pin-on-disk tribometer for friction characterization of various friction sliding pairs. The tribometer setup comprises two high-bandwidth servomotors for the control of the rotating disk and the normal load-related spindle drive, as well as a high-precision tri-axial piezoelectric force sensor for normal and tangential forces measurement. ...
