Mlu based accelerometer using a magnetic tunnel junction

An MLU-based accelerometer comprising:

• at least one MLU cell comprising a tunnel barrier layer between a first magnetic layer having a fixed first magnetization direction and a second magnetic layer having a second magnetization direction that can be varied;
• a proof-mass comprising a ferromagnetic material having a proof-mass magnetization inducing a proof-mass field, the proof-mass being elastically suspended such as to be able of being deflected in at least one direction when subjected to an acceleration vector, the proof-mass being magnetically coupled to said at least one MLU cell via the proof-mass field;
• characterized in that the MLU-based accelerometer further comprises,
• a read module configured for determining a magnetoresistance of each of said at least one MLU cell such as to determine an acceleration vector from the deflection of the proof-mass relative to any one of said at least one MLU cell
• wherein said read module comprises means for switching the second magnetization to a highly sensitive and linear state in which the second magnetization direction is in an intermediary state between parallel and antiparallel to the first magnetization direction;
• and means for determining a degree of alignment between the sense second magnetization direction and the storage first magnetization direction.
