Healthcare • Bioservo Technologies


In Europe, North America and Japan alone, more than 50 million people are estimated to suffer from a weak hand due to illness, injury, stroke or old age. Until now, no real long-term solution has been available to ease their difficulties.

Bioservo SEM™ technology (Soft Extra Muscle) is unique. Other robotic systems under development are heavy and rigid, like a skeleton. However, SEM™ technology uses a completely different design approach. It is lightweight, flexible at the joints and is intended to be worn as clothing. Our mission is to provide modern bionic technology to create innovative, non-invasive wearable aids that strengthen the body’s everyday power and functions.

The technology is applicable to various body parts and is easy to use, even for an entire day. Our first commercial product is the SEM Glove™, that provides extra force and endurance to people with a weak hand grip.

The SEM™ technology concept ventures significantly beyond other state-of-the-art devices by introducing an “intention detection” logic that activates the support if, and only if, the wearer initiates movement with a natural and intuitive movement. This is achieved by sensors that detect the user’s action and strengthens this action by activating the motors. These respond immediately, and in a natural way, to facilitate the intended movement. For the SEM Glove™, the glove detects when the user grasps an object, and the harder the user grasps the more force is applied by the glove.
