Along with temperature monitoring, the other most required physical quantity
to be measured is pressure.
Market offers wide range of solutions including strain gauge, piezoelectric
sensors, MEMS, optical sensor, etc.) covering whole range from industrial
applications to laboratory and testing settings (measuring pressure directly and
indirectly also other quantities).
RVmagnetics MicroWire is a passive sensor – element with no power-wiring
that can be embedded into any material – and able to measure pressure,
strain, torsion, bending, etc. And we do not stop just there. MicroWire is also
able to cover structural health monitoring (SHM), detect cracks inside the
material and even play a key role in predictive maintenance of your products.
A tailor-made sensing solution providing a benefit of its size, range, chemical
resistance and on top of it provide also temperature sensing.
Demonstration of Pressure measurement with MicroWire sensors
With this video we are demonstrating the use of RVmagnetics MicroWire sensors
for detecting pressure.
The main elements of the demo kit: black box which includes the sensing head
and electronics (the size and shape of a final sensing system are tailor made to
meet the space or other limitations ); plastic bar, onto which a stress
dependant MicroWire is attached with an adhesive layer; tablet with the
dedicated app which reflects the signal detection, that also allows one to set
the offset value.
In the video the demonstration happens through pushing and pulling the
plastic bar placed onto the holder. The MicroWire attached to the holder has no
contact with the sensing head, it transfers the signal through magnetic
properties to the sensing head (the black box below). In the Black box (powered
by batteries) contains electronics that create the magnetic field and transfer
the MicroWire’s response via Bluetooth . The signal can be seen in
real-time on the screen of the tablet through the dedicated app
The experiment was held and recorded to prove the feasibility of the
MicroWire sensor and the sensing system,
The system is scalable to the custom needs of our clients and based on
specific requirements can be adjusted. System also allows addressing more
complex tasks such as creating highly accurate pressure distribution
maps or other unique needs of the customer. In the video above, we
presented the basic pressure detection system.
