A wearable system based on a breathable cloth wristband equipped with stretchable strain gauge sensors were assembled and tested to detect a set of 16 different hand gestures. The sensors embedded on the wristband prototype do not require a direct contact with the skin, thus maximizing comfort. To evaluate the performance of the developed band, different gestures were labelled by using grasping information...
Myoelectric (EMG) and mechano-myographic (MMG) signals recorded during muscular activities are useful not only for monitoring and assessing these activities but can also help in providing effective rehabilitation for disabled patients as well as constructing and controlling sophisticated prosthesis for various amputees. While the existing training methods using EMG and MMG signal data have compelling...
Efforts are underway to restore sensorimotor function in amputees and tetraplegic patients using anthropomorphic robotic hands. For this approach to be clinically viable, sensory signals from the hand must be relayed back to the patient. To convey tactile feedback necessary for object manipulation, behaviorally relevant information must be extracted in real time from the output of sensors on the prosthesis...
This study investigated the implementation of a hand model and contact simulation method for the purpose of improving the reality of object manipulation in a virtual environment. The study focused both on the hand tracking method that takes advantage of nails and also contact simulation using a deformable hand model. The manipulation of an object using a hand, is known to make more frequent use of...
The use of prosthetic hands are limited partly due to the fact that they lack the provision of sensory feedback to the user. A first step to providing sensory feedback is having adequate sensors in the prosthesis. The WiseSkin project targets the use of artificial skin embedding ultra-low power wireless sensor nodes. This paper provides an overview of the WiseSkin artificial skin for tactile prosthetics...
