Introduction

Andrew Stuart Troup is a notable inventor based in Cambridge, GB. He holds a total of 4 patents that showcase his contributions to the field of magnetoresistive technologies. His work has significantly advanced the understanding and application of magnetoresistive sensors.

Latest Patents

One of Troup's latest patents is focused on the fabrication of mesoscopic Lorentz magnetoresistive structures. This patent describes a Lorentz magnetoresistive sensor that features an extremely small lead width and lead spacing. The innovative fabrication method allows for the leads to be deposited in a manner where their dimensions are determined by the thicknesses of the lead layers and insulating spacer layers, rather than by traditional photolithography. This advancement overcomes the limitations imposed by photolithographic resolution. Another significant patent involves a magnetoresistance device capable of exhibiting the extraordinary magnetoresistance (EMR) effect. This device includes an elongate channel made of silicon, with a heavily doped silicon conductor connected to one side, allowing for the formation of an inversion layer when a bias is applied to the gate electrode.
