Edible Resonators

The development of green, biodegradable electronics that degrade soon after their function is accomplished is a significant contribution to healthcare where edible electronics can be used for diagnosis. An important component of such systems is a resonator. Here we present the design and development of inductor-capacitor (LC) circuits based on a form of sugar called isomalt. Using its low roughness and mechanical properties, we demonstrate resonators that use capacitors, planar inductors, helical inductors and inductors with an edible core, all fabricated from isomalt.
