NANOSENSORS Membrane-type Surface-stress Sensor (MSS) video uploaded

A new video about NANOSENSORS™ Membrane-type Surface-stress Sensors (MSS) has been uploaded on the NANOSENSORS™ youtube channel.

The NANOSENSORS™ MSS is a piezoresistive nanomechanical sensor: a silicon membrane platform supported with four beams with integrated piezoresistors. This MEMS sensor is very versatile and primarily designed for R&D in the fields of electronic nose/ odor sensing/ olfactory system. It can also be utilized for material assessment application and measurements of physical parameters in, for example, torque magnetometry.

New MSS Sensor for Torque Magnetometry added to the Special Development List

NANOSENSORSTM has completed the development of a new Membrane-type Surface-stress Sensor (MSS) dedicated for torque magnetometry.

Torque magnetometry is a useful technique often employed for assessment of various materials like organic conductors, magnetic and superconductor materials.

Now NANOSENSORSTM has added this new type “SD-MSS-1KTM” to the Special Development list .

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, however, those sensing beams are much longer than in the other two MSS chips (SD-MSS-1K and SD-MSS-1K2G) and form “bending” and “torsional” axes.

For two different functional axes, differently designed piezoresistors are embedded to effectively sense the torque generated by the sample. Considering a use at cryogenic temperatures, the resistance of the piezoresistor is designed relatively low and in the range of 0.3 – 1.2 kΩ. Each piezoresistor can be individually connected so that various measurement configurations can be arranged by the user.

Compared to the conventionally used piezoresistive cantilevers, the new type of Membrane-type Surface-stress Sensor “SD-MSS-1KTM” has many advantages:

  • easier to handle the chip
  • relatively robust structure
  • larger sample capability, etc.,

all of which facilitate preparations of measurement setup and increase turnaround of material assessment.

NANOSENSORS introduces MSS-8RM – a readout module for membrane-type surface stress sensors (MSS)

The NANOSENSORS Membrane-type Surface-stress Sensor (MSS) is a device to detect specific components in gaseous phase with high sensitivity using a piezoresisitive nanomechanical sensor. This device shows great potential as a core component for electronic-nose (olfactory) systems utilized in e.g., medical, food, environment, safety and security fields.
Now NANOSENSORS™ introduces the MSS 8 Channel Readout Module (MSS-8RM), a basic electronic module to operate and to readout NANOSENSORS™ MSS, up to 8 sensors simultaneously, under a hardware configuration for electronic-nose sensing. MSS-8RM contains two air pumps and users can examine “self-prepared” MSS (compatible: SD-MSS-1K and SD-MSS-1K2G) under different gas flow conditions.

MSS-8RM is designed as simply as possible so that users can learn about a basic electronic-nose system and further improve the system performance. MSS-8RM does not include any data processing functions to distinguish one sample from the other. Users will obtain raw numerical data of the sensor responses under different conditions as final output.
