Carbon hand: Get a Grip - Bionic hand orthosis from Bioservo

• The CARBONHAND® bionic hand orthosis offers new strength and endurance for weak hands.
• It strengthens the existing grip strength and enables holding and grasping objects.
• Sensors in the fingertips react to the slightest changes in pressure and amplify the gripping movement performed.
• Artificial tendons are used to strengthen the existing muscles. These tendons shorten in real time and cause the fingers to bend. An object can be held forcefully with up to 20 N.

The Carbon Hand (also from Bioservio) is a hand orthosis for people with Grip weakness (in case of complete functional failure of the hand, it cannot be used). It amplifies gripping movements, i.e. when the user touches an object and applies very light pressure, this pressure is multiplied by the orthosis.

There are sensors on the fingertips that are connected to artificial tendons and a small battery-powered device.

The orthosis is like a glove that covers the thumb, ring and middle fingers.

These are connected by artificial tendons to a small, battery-powered device that the user wears on a belt, for example. The gripping movement is reinforced by a contraction, i.e. shortening, of these artificial tendons.

Touch sensitivity and pressure of the sensors can be adjusted individually and for each finger via app.

The effect of Carbonhand is immediate. With an applied force of up to 20 Newtons (N) per finger, a majority of patients with limited hand strength can regain most of their hand function and resume activities and household tasks. In addition, several studies conclude that many patients enjoy a stronger grip, improved hand function and a more independent life, even when the Carbonhand is removed.
