Micro-machined sensor, particularly for displacement
TLDR
In this paper, a micro-machined inductive sensor emits an alternating magnetic field in order to detect position and or movement of an object (O), which is capable of modifying the magnetic field, by means of a discontinuity (D,C).Abstract:
Micro-machined inductive sensor emits an alternating magnetic field in order to detect position and or movement of an object (O), which is capable of modifying the magnetic field, by means of a discontinuity (D,C). The sensor comprises a planar emitting coil (10), which radiates the alternating magnetic field and one or more planar receiving magnetic coils (11-14), arranged in such a manner as to capture a certain part of the radiating field and variations in the field caused by discontinuities in the object (O). The coils are machined on the common substrate by a selective photolithography process. In the areas where the emitter coil (10) is contiguous with the receiver coils (11-14) a shielding strip galvanically independent of the coils (10-14) is connected to a reference potential. The shielding strip is formed by deposition of a metal skin on the substrate.read more
