Researchers from the University of Houston and China have described 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. Cook assistant professor of mechanical engineering at the University of Houston and lead author of the paper.
The work is published in the journal Science Advances.
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.
“More importantly, the transient period of time can be precisely controlled,” he said.
