We report on a new type of micromachined probe card which utilizes fritting process to make contact to Al or Cu pads with low contact force smaller than 10 mN. Microcantilevers contacting the pad surface with buckling deformation and can keep uniform contact force were designed and fabricated. Mechanical properties of the micro-cantilever was measured and a good agreement with theoretical buckl...

Tactile roughness magnitude estimates increase with contact force. However, it is not known whether discrimination thresholds are affected by contact force and other parameters, such as duration and tangential movement. The effects of these factors on roughness discrimination thresholds were determined using an adaptive staircase procedure for coarse and fine texture discrimination during activ...

The ability to predict patient-specific joint contact and muscle forces accurately could improve the treatment of walking-related disorders. Muscle synergy analysis, which decomposes a large number of muscle electromyographic (EMG) signals into a small number of synergy control signals, could reduce the dimensionality and thus redundancy of the muscle and contact force prediction process. This ...

The measurement accuracy of vibratory surface finishing forces (VSFFs) are seriously affected by the wiring force sensor, because trajectory sensor with is significantly different that workpiece without wiring. To solve this problem, a triaxial wireless (WFS) developed to measure VSFFs between media and surfaces in under various operation conditions. Experimental results show normal impacts dom...
