Working closely with therapists, Emovo Care has developed a lightweight and easily attachable arm exoskeleton for people unable to hold objects after a stroke or accident. The device has been successfully tested in several hospitals and rehabilitation centers.

The company’s engineers have been developing Emovo Grasp for several years with the help of people with disabilities, and then improved it during several rounds of testing in hospitals and rehabilitation centers. The company recently received the European ISO certification required to market its product as a medical device.

Emovo Grasp consists of two patented artificial tendons, similar to thin cables, inserted into a sheath. They are attached along the back of the hand with silicone rings worn on each finger. The motor and remote control, which allows the user to adjust the applied force, are in small separate cases. This design frees up the palm and fingertips to maximize touch input.

Biologically engineered artificial tendons are similar to the natural muscle and tendon system in the hand. The device never acts on its own – the user is always in control of the situation so as not to drop things or grab them at the wrong moment.
