Big hopes for muscle-like material

Unique physical properties found in Ras Labs synthetic muscle has drawn the interest of prosthetics makers and hospitals.

What it does

The engineered material has yet to be shaped into usuable forms. Its properties:

It is resilient at extreme temperatures.
The gel can be rehydrated if it dries out.
It expands and contracts when electricity is run through it.

How it works

1

When a current is run through the gel, it contracts like a flexed muscle.

2

When the current is reversed, it expands.

On the drawing board ...

Although the artificial muscles exists only in the lab right now, improving the fit and comfort of prosthetic liners is seen as a first step.

Down the road ...

Lenore Rasmussen hopes it can be shaped into artificial muscles that can help operate more sophisticated and functional arm and hand prostheses.

A synthetic muscle-lined sock would expand to the contours of the patient’s limb.
