substantial displacement by bending a cantilever (Figure 7.11a). This bending motion
can directly be used to stretch the skin without the need for extra motion amplification
mechanisms. Figure 7.11b shows the manner in which a collection of bending elements
can be arranged to create a two-dimensional array of contactors. One advantage of this
design is the creation of a strong, yet modular, structural configuration made of the same
part replicated 10 times. Although all contactors move along the same direction due to the
