KnitRegen: Making smart stroke therapy more portable

The challenge

Current estimates suggest that 1 in 4 people are likely to experience a stroke during their lifetime, and around 50% of stroke survivors experience moderate-to-severe problems using one of their arms.

CPI worked with KnitRegen to develop its wearable stroke rehabilitation prototype through our Sonnet programme. We collaborated to make the technology portable – reducing its bulk from the size of a backpack to a wristband and integrating a rechargeable Bluetooth-enabled battery. We also made it safer and more energy efficient by reducing the power required to stimulate muscles.

CPI designed the electronics that enabled us to repackage our technology into a wearable and portable form. The collaboration has also enabled us to rigorously test all the components to meet safety standards. We can now bring this technology to more people to help with their stroke rehabilitation.

How CPI helped

• Developed approaches to improving the prototype. 
• Provided electronics and firmware design expertise and bespoke electronic components. 
• Conducted a feasibility study on the actuator that stimulates the muscles. 
• Consulted on the future development of the product. 

Achievements

• Streamlined electronics and key components to create a more portable wristband version of the prototype. 
• Created a Bluetooth-enabled device utilising rechargeable batteries with safety controls. 
• Integrated an auditory ​‘click’ as an acoustic cue for the device. 
• Replaced the actuator with one that uses less power to produce mechanical impulses, making it safer and more efficient.
