This equipment can measure continuous strain along an optical fiber over a distance of 10 km.
Long-term continuous strain recordings were made using an implantable telemetry device able to read out bone-bonded strain gauges.
Figure 4b shows the current response of a continuous strain ranging from 0 to 160% of the PANI/TPU sensor.
From the current response to the continuous strain, we can see that the sensor has good stability.
The paper also presents an approach for the derivation of load-transfer curves from continuous strain data.
The progressive opening of the cracks is studied using PIV, and continuous strain fields during cracking are provided.
It inevitably induces continuous strains in the lower lumbar spine of the seat occupant and is therefore a possible source of LBP.
For a geometrically nonlinear setting we suggest a new general method to design continuous strain-type sensors for measurements in the vicinity of a known pre-deformed state.
A regularization routine is included in a variational procedure in order to minimize potential energy in the body and produce continuous strains at cell borders in the grid.
This approach will produce a continuous strain (second order) tensor, except on a number of surfaces where material discontinuities are present.
