Orthotic devices are tools which are applied to the human body to align, support, or correct deformities, or to better the movement of joints, spine, or limbs.
Researchers at Taiwan's Industrial Technology Research Institute have developed a new sensitive tactile film to use in orthotic devices for people with essential tremor. Essential tremor is a neurological disorder that causes a rhythmic shaking.
‘Higher Sensitivity Tactile-film System for Wearable Orthosis (HSTS), a new technology, with the help of the thin film detects the pressure regions on the orthosis exerted by the arm to identify the involuntary tremors and movements. ’
AdvertisementThe new technology is known as Higher Sensitivity Tactile-film System for Wearable Orthosis (HSTS). The technology with the help of the thin film detects the pressure regions exerted by the arm on the orthosis. This allows the device to identify the involuntary tremors and movements initiated by the user.
Tactile film, data acquisition computer, the software that processes the data, and the robotic orthosis are the main parts of the system.The robotic orthosis moves in response to user intentions.
The film has tactile sensor arrays (basically to measure information arising from physical interaction with its environment) and has benefits over electromyography (EMG) to control an orthosis for people with tremor.
The tactile sensor is not affected by skin temperature and hydration, and can assess the difference between a tremor and intended movement with relative ease.
