Purpose of the development: The sensors are designed for use in collecting data on the linear deformation, the object moves, the pressure changes or unauthorized access.

Recommended application field: Engineering and instrumentation, security systems, laboratory and teaching equipment.

Advantages over analogues: The proposed detector can be manufactured in any size and be positioned in a large area. Control scheme does not require continuous monitoring of the strain gauge transducer. Poll tensor converters held alternately by a given algorithm with any sampling rate and with only one computer, which greatly reduces the cost of measurement. The cost of the instrument: 5-50 USD.

The development stage readiness: The working documentation is developed

Description of the development:
()
Technical capabilities ( brief description ) : - The benefits of the property caused by the pressure sensor sensing element compressible . So at strains over 5 N/cm2 strain sensing element is irreversible , that is, after removal of the load resistance is fixed at a particular value . With the passage ( passage ) zone sensor human, animal or vehicle electrical resistance converter abruptly changes from R0 to R1 value and remains at R1 after unloading . R1 is a value in the range of (0,1-0,2) R0 depends on the momentary load force . At any time, impedance control tenzopreobrazovatel shows took place (R1) or not (R0) unauthorized access . - Longitudinal deformation of the substrate of the sensor leads to a sharp surge resistance of the sensitive element with subsequent stabilization over time. Linear strain sensors based on percolation sensitive elements of 1-3 % change in conductivity to give 50-500 %.
