Researchers from the University of Houston and China have reported a new type of electronic device that can be triggered to dissolve through exposure to water molecules in the atmosphere.
The work holds promise for eco-friendly disposable personal electronics and biomedical devices that dissolve within the body.
There are also defence applications, including devices that can be programmed to dissolve in order to safeguard sensitive information, said Cunjiang Yu, Bill D.
The field, known as physically transient electronics, currently requires immersion in aqueous corrosive solutions or biofluids.
Yu said this work demonstrates a completely new working mechanism – the dissolution is triggered by ambient moisture.
