As a leader in the field of connectivity, we see firsthand what a positive impact technology can have on people's lives.
Fischer Connectors is proud of its partnership with TWIICE, an exoskeleton of the lower limbs that allows people with paraplegia to get up, walk and climb stairs. One of the lightest and most compact portable robotic supports in the world, TWIICE helps its users gain independence and mobility.
As a partner of TWIICE, we have made our connectivity solutions, experience and technical expertise available to help create a medical assistive technology that is as powerful as it is easy to use.
Since each handicap is unique, the challenge was to create a modular and easily customizable device to fit the users’ different morphologies and pathologies. TWIICE's team of design engineers chose the Fischer Core Series AluLite™ and Fischer Freedom™ (plastic version) connectors for their reliability and robustness, their compactness and ultra-lightness, as well as for their usability and integrability.
TWIICE's connectivity was facilitated by:
- a choice of solutions offering an optimal weight-to-performance ratio;
- compact, high-density connections for maximal comfort and control;
- the guarantee of reliable, safe products to protect the user from injury.
The project: constantly evolving
TWIICE ONE is the very first walking assistance exoskeleton developed in 2016 at the Laboratory for Robotic Systems (LSRO) of the Swiss Federal Institute of Technology in Lausanne (EPFL). Designed as a modular robotic device, the project is constantly evolving. An adaptation of TWIICE ONE was developed in 2020 to allow paraplegic people to go ski touring: WIITE. Improvements and innovations are planned in order to keep adapting the device to other specific needs.
Internationally recognized, TWIICE's technology has been presented at numerous events aimed at promoting innovation and research in this particular field of medical robotics, including the Cybathlon. During the 2020 edition of this international sports competition for athletes with a physical disability, the TWIICE team and pilot Silke Pan won the silver medal in the “Powered Exoskeleton Race” (EXO). The participants in this competition are all equipped with an exoskeleton and compete against each other in a timed race involving daily tasks like going up and down stairs, opening, going through and closing doors, and passing obstacles fixed to the ground.
How does TWIICE work?
TWIICE and, by extension, WIITE, is an articulated system that attaches to a patient’s knees and hips, and supports their legs, thighs and upper body. It contains tiny electric motors that bend and extend the knee and hip joints to replicate the body’s natural movements during walking and backcountry skiing. It runs continuously on a two-hour battery housed in the dorsal part of the system. Patients can carry spare batteries (which weigh less than 1 kg each) in a separate backpack. The exoskeleton’s dedicated electronics carry out the wearer’s instructions securely and reliably.
Through our partnership with TWIICE, we are turning ambitious ideas into reality by helping people with paraplegia to stand, walk and gain independence and mobility, thereby improving their quality of life.
