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 firstname.lastname@example.org
The authors of the article demonstrate what other papers have already talked about in the past: it is possible to use probes like the NANOSENSORS Uniqprobe qp-CONT as basis to make working probes for NSOM or TERS, by using radially polarized light. They go a step further by FIB tailoring the metal film that fully covers the transparent tip.
Congratulations to the authors!

A lot of work was done by research groups at the University of Neuchâtel, more than 10 years back, demonstrating the high resolution properties of microfabricated apertureless (fully metal coated) transparent quartz tips, where a connection between the observed high spatial resolution and longitudinally polarized fields confined at the probe apex was observed. The authors gave direct experimental evidence that, after injection of a radially polarized beam, a confined single spot is produced at the tip apex.
