A set of schemes for automated discrimination of gait patterns based on recognition of surface electromyogram (sEMG) of human lower limbs is proposed to classify 3 different terrains and 6 different movement patterns. To compare the recognition performance of different classifiers, Back Propagation Neural Networks (BPNNs) and Process Neural Networks (PNNs) are deployed to discriminate gait patterns...
We propose an easy method to pattern the surface charge of electrets without patterning the dielectric layer. By eliminating the use of metal guard electrodes, both the charge efficiency and the surface charge stability in humid environments improve. We apply the concept to a vibrational energy harvesting device, where a power output of 3 is successfully harvested at a low...
We demonstrate an application of three-way flexible micro four-point probes for indirect uniformity characterization of surface morphology. The mean sheet conductance of a quasi-planar 3D nanostructured surface is highly dependent on the surface morphology, and thus accurate sheet conductance measurements may be useful for process uniformity characterization. The method is applied for characterization...
