Found this press release interesting.
Engineers at Oregon State University have developed and successfully demonstrated the value of a simple pulley mechanism to improve hand function after surgery.
The device, tested in cadaver hands, is one of the first instruments ever created that could improve the transmission of mechanical forces and movement while implanted inside the body.
Personally, I found it to be related to robotics. Nevertheless, according to the Oregon State University's spoke person, it is NOT robotic.
The new mechanism developed at OSU is not really robotic since it has no sensory, electronic or motor capabilities, Balasubramanian said. Rather, it’s a passive technology using a basic pulley that will be implanted within a person’s hand to allow more natural grasping function with less use of muscle energy.
