New sensory feedback technology aims to transform upper limb prosthetics
Prosthetic specialist COVVI has announced the upcoming launch of COVVI Touch, a new sensory feedback module designed to enhance functionality for people who use upper limb prosthetics.
When paired with the COVVI bionic hand, COVVI Touch will enable sensors in each digit to detect when an object has been grasped. A vibrational response is then relayed to the user’s residual limb, helping to create a sense of touch.
The company says the technology has been developed to address a common limitation of many bionic devices, where users often rely heavily on eyesight to complete everyday tasks accurately. This can be particularly challenging during activities that require both hands or involve multiple focus areas.
COVVI Touch will provide personalised and programmable sensory feedback from all five digits of the bionic hand, which COVVI describes as an industry first.
Traditionally, information is passed one way from the user’s limb, through their socket, and into the prosthetic hand. With COVVI Touch installed, information can be transferred both ways, allowing the user to receive touch feedback in as little as 0.5 seconds.
Simon Pollard, CEO of COVVI, commented: “We are unlocking technology that was built into the foundations of the COVVI Hand.
“Touch sensing technology equips our users with more tools than ever before to tackle daily tasks. I am pleased to say that, after so much hard work, we have created a sensory module that succeeds in doing just that – adding to the already tangible difference that we are making to the lives of our users.”
Clinicians and users will be able to configure COVVI Touch through COVVI’s app, tailoring how feedback is received. Adjustable settings include which grips generate feedback, the strength of the vibration, and how feedback is delivered, such as through a single pulse, continuous vibration during contact, or a recurring pulse.
COVVI Touch can also help users better understand the size of an object. The vibration increases in intensity depending on how many digits are in contact with the item, providing an additional layer of information during use.
The development marks a significant step forward in prosthetic hand technology, with COVVI aiming to give users greater confidence, independence, and control when carrying out everyday activities.
In 2025, COVVI introduced a state-of-the-art multi-articulated hand that is able to complete complex tasks.
