R&D News: New MSS Sensor Dedicated for Torque Magnetometry under Development

In a recent blogpost we shared the news that NANOSENSORSTM Membrane-type Surface-stress Sensors (MSS) could successfully be used for torque magnetometry .

We have therefore decided to develop a new MSS series sensor chip that is dedicated to measure force and torque.
The new sensor chip will be called SD-MSS-1KTM and is currently in the beta testing phase.

The new sensor chip shares the common MSS features, i.e., a membrane (or platform) supported with four beams on which piezoresistors are embedded at the fixed ends.

In the newly developed sensor chip dedicated for torque magnetometry however, those sensing beams are much longer than those of the currently available MSS chips and form “bending” and “torsional” axes.

Further technical information will be announced upon an official product release. For any other questions or requests please contact us at info@nanosensors.com

New Method for Torque Magnetometry Using a Commercially Available Membrane-Type Surface Stress Sensor

In this article the authors present a  new method for torque magnetometry by using a commercially available membrane-type surface stress sensor (MSS) – the NANOSENSORS MSS. This sensor has a silicon membrane supported by four beams in which piezoresistive paths are integrated. Although originally developed as a gas sensor, it can be used for torque measurement by modifying its on-chip aluminum interconnections. The authors demonstrate the magnetic-torque measurement of submillimeter-sized crystals at low temperature and in strong magnetic fields. This MSS can observe de-Haas–van-Alphen oscillation, which confirms that it can be an alternative tool for self-sensitive microcantilevers.
