Myoshirt: Wearable Textile Exomuscle #WearableWednesday

There are many reasons one might experience a weakening of the muscles. Recently, researchers have developed an exosuit that can augment muscle strength. Here’s more from Wearable Technology Insights:

“My arms are simply getting weaker,” says Michael Hagmann, who was diagnosed with a rare form of muscular dystrophy known as Bethlem myopathy back in 2016…. Marie Georgarakis, a former doctoral student at ETH Zurich’s Sensory Motor Systems Lab, is familiar with the problem. “Although hospitals have numerous good therapy devices, they are often very expensive and unwieldy. And there are few technical aids that patients can use directly in their everyday lives and draw on for assistance in performing exercises at home. We want to close this gap,” says Georgarakis.
This idea led to the creation of the Myoshirt: a soft, wearable exomuscle for the upper body. It is a kind of vest with cuffs for the upper arms accompanied by a small box containing all the technology that is not used directly on the body. Working via sensors embedded in the fabric, a smart algorithm detects the wearer’s intentional movements and the amount of force required. A motor then shortens a cable in the fabric running parallel to the wearer’s muscles – a sort of artificial tendon – and in this way supports the desired movement. This assistance is always in tune with the user’s movements and can be tailored to their individual preferences. The user is always in control and can override the device at any time.
