?? Theoretically backed performance of direct concrete stress measurement
    with no conversion from a detected strain quantity.
?? Receive minimal effects of creep and changing elastic modulus of concrete.
    and there by ensure accurate stress measurement.
?? Also usable for stress measurement of the natural ground by installing
    at the rear of a tunnel lining.
