Dissolvable Electronics

Many modern technologies wouldn’t be possible without recent advances in semiconductor materials—but even the tiniest, fastest, most advanced semiconductors have their limits. S.-K. Hwang et al. present a proof-of-principle for a new class of electronics that are designed to degrade and completely disappear over a prescribed period of time. Such devices could be used not only for biomedical and environmental monitoring but also as a strategy for reducing electronic waste.
