Abstract:
1. A sensor system for monitoring bodily functions comprising at least one sensor having attachment unit to be attached to external body skin at two separate locations for providing indications of skin deformation between the two locations, wherein the sensor comprises two generally planar coils juxtapositioned with a spacing in between wherein one of the coils functions as an excitation coil and the other as the output coil, and one of the coils is adapted to be connected to the skin, a metallic shield positioned within the coil spacing being adapted to be attached to the skin, wherein the shield and the coils are movable with respect to each other to follow deformations of the skin between the attachments of the coil and shield to provide indications of movement in the form of changes of the amount of magnetic flux transmitted between the coils.
