Note that, in practice, piezoresistive elements may be arranged in several ways to sense pressure, such as in the diagram. Most force sensors are based on an elastic or spring element: the force generates a deformation that is measured by some displacement sensor (as discussed in previous chapters). A load cell is a type of transducer that measures the mechanical load on an object by converting it to readable electronic signals. The dual-mode pressure sensing device consists of a cylindric elastomer, a piezoelectric unit and a piezoresistive unit as depicted in Fig. E: Sci.
