Flat Type Thick Film Inductive Sensors

open access: yesActive and Passive Electronic Components, 2003
Two thick film flat-type inductive sensors are described and tested for distance and profile measurement. The first one is a single-layer spiral while the second one is a multi-layer structure consisting of ten spirals one over the other.

Design and Test of a New Inductive Force Sensor [PDF]

open access: yesSensors, 2018
The currently accepted interval of weekly cast changes in the treatment of clubfeet seems unsubstantiated. A force sensor is needed to determine the adaptation rate of a clubfoot to establish what cast change interval would be most effective and efficient.
