Contactless rotational concentric microviscometer

Peter Ryser, Eric Meurville, Sigfrid Straessler, Emeric Grandjean

We investigated the feasibility of a concentric rotational microviscometer which is actuated remotely. This type of sensor might find application in vivo as a passive implant. The heart of the sensor is a cylindrical rotor, actuated from a distance of up t ...
