The video on NANOSENSORS™ Membrane-type Surface-stress Sensors (MSS) for olfactory sensing has just passed the 500 views mark. Thank you all for watching.
The NANOSENSORS Membrane-type
Surface-stress Sensor – MSS is a non-packaged MEMS sensor, a silicon membrane
platform supported with four beams on which piezoresistors are embedded. It is mainly dedicated to R&D in the areas
of olfactory sensing and electronic noses.
There are currently two major applications for this type of sensor:
the MSS has a great potential as a core component for electronic (artificial) nose systems / olfactory sensing systems utilized in e.g., medical, food, environment, safety and security fields.
the MSS can also be used for assessment of various materials like organic conductors, magnetic and superconductor materials in torque magnetometry.
dielectric permittivity of membranes is important for many fundamental
electrophysiological functions like selective transport in ion channels, action
potential propagation and energy generation.*
article “Nanoscale dipole dynamics of protein membranes studied by broadband
dielectric microscopy” George Gramse, Andreas Schönhals and Ferry
Kienberger investigate the nearfield dipole mobility of protein membranes in a
wide frequency range from 3 kHz to 10 GHz.*
achieved their results by adding the frequency as a second fundamental
dimension to quantitative dielectric microscopy thereby demonstrating the possibilities
of broadband dielectric microscopy for the investigation of dynamic processes
in cell bioelectricity at the individual molecular level. Furthermore, the
technique may also shed light on local dynamic processes in related materials
science applications like semiconductor research or nano-electronics.*
