Biodegradable Elastomers and Silicon Nanomembranes/Nanoribbons for Stretchable, Transient Electronics, and Biosensors
Transient
electronics represents an emerging class of technology that exploits
materials and/or device constructs that are capable of physically
disappearing or disintegrating in a controlled manner at programmed
rates or times. Inorganic semiconductor nanomaterials such as silicon
nanomembranes/nanoribbons provide attractive choices for active elements
in transistors, diodes and other essential components of overall systems
that dissolve completely by hydrolysis in biofluids or groundwater.
We describe here materials, mechanics, and design layouts to achieve
this type of technology in stretchable configurations with biodegradable
elastomers for substrate/encapsulation layers. Experimental and theoretical
results illuminate the mechanical properties under large strain deformation.
Circuit characterization of complementary metal-oxide-semiconductor
inverters and individual transistors under various levels of applied
loads validates the design strategies. Examples of biosensors demonstrate
possibilities for stretchable, transient devices in biomedical applications
