Edinburgh-based startup Metacarpal, which is behind what’s thought to be the world’s first mechanical bionic hand, has secured £800,000 in seed funding to accelerate its prosthetic development.

Investors in this funding round included SIS Ventures, Scottish Enterprise, Worth Capital, Oxford Technology, the University of Strathclyde, and Gabriel Investment Syndicate.

The Scottish firm has used advanced engineering techniques to create a highly-functional prosthetic hand that is completely controlled and powered by body motion, and without the need for electronics.

The bionic hand combines the practicality of body-powered control with the functionality of a myoelectric prosthetic—including five-finger motion, variable grips, and wrist positions.

The business was founded by University of Strathclyde product design engineering graduate Fergal Mackie in 2020, and was inspired by an accident he had in the final year of his studies.

After falling over and breaking both of his wrists, Fergal had to discover new ways to complete his daily tasks, sparking an interest in prosthetics.

As it stands, the majority of development in prosthetics globally has focused on robotic hands, leaving a large gap in the market for body-powered devices.

By providing this alternative, Metacarpal aims to enhance the acceptance rate of prosthetics, ultimately improving long-term health outcomes for individuals with limb differences.

The funding boost will enable the startup to finalise the product, begin manufacturing units, and double its headcount to eight.

The ultimate ambition is to change the lives of those with limb differences, while continuing the development of technology and expanding its capabilities in prosthetics.

Fergal Mackie, who’s CEO and founder of Metacarpal, said: “Metacarpal was established to create a better quality of life for amputees.

“With the use of truly revolutionary, unique and disruptive technology, our body-powered bionic hand is raising the standard of upper-limb prosthetics. It is the only device to utilise reactive body-power technology giving fingers individual motion.

“The success of the seed funding round is a huge milestone for the business, which will enable us to develop our bionic into a commercially viable product with the potential to change the lives of prosthetics users. I cannot wait to see the impact that it has”
