Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in /home/clients/89f5f0444c120951cfdb7adc5e3aa2bf/web/dev-nccr-robotics/wp-includes/pomo/plural-forms.php on line 210 Soft Sensors and Actuators – NCCR Robotics
Within NCCR Robotics we use advances in the fields of soft robotics and materials science to create small conductive materials that can be used to replicate and reproduce naturally occurring neurological signals in people who, through reasons of disease or injury, have lost use of limbs due to electrical impulses not being transmitted correctly.
e-dura: The e-dura was first published in 2015 and is a soft and stretchable implant which can be directly placed beneath the dura mater, the nervous system’s protective casing, and onto the spinal cord for months at a time.
Composite Thread that Varies in Rigidity: This fibre has a metal core, consisting of low melting point alloys (LMPA), which is contained within a pre-stretched silicone tube. At room temperatures the LMPA is a solid, thus the fibre is stiff and behaves like a thin metal wire. But when an electrical current is passed through a copper wire coiled around the tube, the LMPA inner core is warmed above 62 oC and melts, thus the fibre becomes up to 700 times softer and 400 times more deformable.
Stretchable solid-liquid electrical film: A thin (<1 micrometre thick), lightweight and extremely versatile film.
