piezoresistive sensor

[pē¦ā·zō·ri¦zis·tiv ′sen·sər]
(engineering)
A transducer which converts variations in mechanical stress into an electrical output; it consists of an element of piezoresistive material that is connected to a Wheatstone bridge circuit and is placed on a highly stressed part of a suitable mechanical structure, usually attached to a cantilever or other beam configuration.

These sensors have already been evaluated for this type of application, and we found it is the best choice over other piezoresistive sensors, as they have a wider range and low hysteresis, which implies that this sensor can be used for ascending or descending loads (Enriquez-Rivera et al.
