The Omni Hand prosthesis uses optical sensors that read signals not only from muscles, as in traditional systems, but also from tendons in the wrist. The technology is based on detecting changes in tissue light transmittance when a person tenses or relaxes their hand, altering blood flow and ligament positioning.
Various studies on applying optical technologies in prosthetics have been conducted since 2016, when scientists reported on the possibility of using stretchable optical waveguides for sensors in hand prostheses. The uniqueness of Motorica's development lies in the specific implementation of the technology, using optical sensors to read signals. This enables recognition of phantom limb movements meaning movements that users mentally perform with their lost hand.
Omni Hand can memorize up to six unique movements and reproduce them in any order. Therefore, the device is suitable for patients with weakened muscles, after electrical injuries, frostbite, or other damage. Before launching serial production, pilot testing is underway: eight people have already received the prostheses and are using them on a permanent basis.
Motorica is Russia's largest manufacturer of bionic limb prostheses and assistive devices. Since 2015, the company has produced over 8,000 products. In 2024, Motorica acquired a controlling stake (50.1%) in Zavod Spetsyalnogo Oborudovaniya LLC, one of Russia's largest wheelchair manufacturers with a production volume of over 40,000 units per year. In 2026, the company is preparing for an IPO.
