For decades, walking frames have been a case study in stagnation. They've remained almost unchanged since their invention, functional, yes, but limited in how they adapt to real-world conditions. Traditional frames can be awkward to maneuver on slopes, unstable on rough terrain, and visually uninspiring. More importantly, they often carry a stigma, subtly signaling frailty rather than empowerment. US-based startup Mobilate saw this as a glaring opportunity.
The onset of motor neurone disease (MND) left Sarah without a voice and the use of her hands at the age of 34. It was within months of her becoming a mum for the second time. As they were growing up, her children Aviva and Eric only ever heard her speak through a machine with an emotionless robotic voice. But 25 years on, artificial intelligence (AI) has recreated their mum's real voice from just eight seconds of audio on a scratchy VHS tape.
"Our main goal is creating a flexible speech neuroprosthesis that enables a patient with paralysis to speak as fluently as possible, managing their own cadence, and be more expressive by letting them modulate their intonation," says Maitreyee Wairagkar, a neuroprosthetics researcher at UC Davis who led the study.
"In the wake of a long-haul injury, the importance of outside design perspectives cannot be overstated, as they may highlight overlooked problems and reveal useful solutions."
