Fig. 5.13 Injectable electronics for soft mater. a,b, Optical images of PDMS cavity before
injection (a) and the hybrid structure of injectable devices embedded in PDMS after injection (b).
cSchematic of electronics injected and cured in cavity of PDMS with I/O pads unfolded outside
the cavity (I). Red, SU8; Yellow, metal/SU8; Blue, nanodevices. Micro-CT image (II) shows the
zoomed-in structure highlighted by the black dashed box in (b) and (c, I). Pseudocolors are
applied: Yellow, metal; Purple, PDMS.d11 nanowire devices response to point loading on the
PDMS. The downward and upward pointing triangles denote the times when the strain was applied
and released, respectively. The upward and downward arrows show the compressive and tensile
strains, corresponding to the plus and minus change of conductance respectively
