Modulus matching can guide the design of flexible and biointegrated electronic devices. The mechanical properties of various classes of materials used in microfabricated electronic devices (top) and organs in the human body (bottom) are plotted on a logarithmic spectrum of mechanical modulus. Materials traditionally used in microelectronic device fabrication (e.g. silicon, oxides, and metals) exhibit Young’s moduli that are orders of magnitude larger than the excitable tissues with which they are intended to interface including the peripheral nervous system. There are opportunities to engineer PNI with stretchable and ultracompliant electrode materials that can better match the mechanical properties of the target tissue
