introduction: foot insoles are widely recommended to prevent running related to injuries. however, their effects on the frequency of ground reaction force(grf) is still unclear. the purpose of this study was to elemental test the effect of four shoe insoles on frequency of grf during stance phase of running. materials and methods: 15 female students (mean age22±1/85 year, height162±4/71cm and w...

The purpose of this study was the experimental validation of the OpenGo sensor insole system compared to PedarX sensor insole and AMTI force-plate systems. Sixteen healthy participants performed trials in walking, running, jumping (drop and counter movement jumps), imitation drills and balance, with simultaneous measures of all three systems. Detected ground contact and flight times with OpenGo...

ticle as: T.-C. Hou p://dx.doi.org/10 Abstract We report a simple fabrication, great performance and cost-effective triboelectric nanogenerator (TENG), which is based on the cycled contact-separation between a polydimethylsiloxane (PDMS) film and a polyethylene terephthalate (PET) film, for effectively harvesting footfall energy. The elastic sponge is first used as the spacer in the TENG, where...

Insole pressure sensors capture the different forces exercised over the different parts of the sole when performing tasks standing up such as walking. Using data analysis and machine learning techniques, common patterns and strategies from different users to achieve different tasks can be automatically extracted. In this paper, we present the results obtained for the automatic detection of diff...

Inadequate postures adopted by an operator at work are among the most important risk factors in Work-related Musculoskeletal Disorders (WMSDs). Although several studies have focused on inadequate posture, there is limited information on its identification in a work context. The aim of this study is to automatically differentiate between adequate and inadequate postures using two wearable device...

This paper proposes a novel and an affordable lower limb prosthesis to enable normal gait kinematics for trans-femoral amputees. The paper details the design of a passive prosthesis with magneto-rheological (MR) damping system and electronic control. A new control approach based on plantar insole feedback was employed here. Strategically placed sensors on the plantar insole provide required inf...
