Ultra-sensitive, Miniature, Low Power, Inexpensive Magnetometer

By Nati Fisher | December 17, 2020

The Problem

Currently, available inexpensive and miniature commercial magnetic sensors exhibit field resolution of hundreds of picotesla and above, while commercial sensors with field resolution of few picotesla and below are normally much larger and more expensive and in some cases operate only at cryogenic temperatures. Namely, there are no commercial magnetic sensors which are miniature and inexpensive and still exhibit field resolution of few picotesla.

The Solution

Innovative magnetic sensors which are based on the Planar Hall Effect (PHE).

The Commercial Benefit

Our novel sensors offer several significant key advantages:

  • Field resolution of several picotesla @ 1 Hz
  • Low cost
  • Low power consumption (few milliwatts)
  • Small dimensions (few millimeters)
  • Operation in a wide range of temperatures, including room temperature

Market Potential

The global magnetic field sensor market is expected to reach USD 5.37 Billion by 2023, growing at a CAGR of 8.77% between 2017 and 2023. The demand for reliable, high-performance, and low-cost sensors is increasing.
