Electronics that dissolve on command

A researcher from the University of Iowa involved in the creation of "transient materials"

Imagine a credit card that will completely dissolve, once in the hands of a thief. Or secret diary with self-destruct mechanism in case it detects an intruder. All this will soon be possible thanks to the "fleeting material."

Usually electronic devices are expected durability and high reliability, enabling devices to serve people over a long period of time.

But studies are underway and in the opposite direction. Electronics, able to disappear without a trace, can be widely applied e.g. in medicine or in military and commercial applications.

A group of researchers from the University of Iowa has focused its efforts on the creation of a "fleeting material", which can melt away by remote command.

These materials were created a long time ago, they have managed to produce soluble transistors, resistors and diodes. Iovskoe researchers have focused their efforts on the ability to control electronic devices.

The researchers conducted a series of experiments by mixing a biodegradable polymer film. Managed to install, for example, that with the addition of gelatine to the mixture, the dissolution process was slowed down. And here is sucrose, on the contrary, bystraia the disappearance of the materials.

Using these solutions, the team was able to construct and test an antenna, able to receive and send data, and dissolve upon receiving the special signal.

Although this area of electronics is still insufficiently developed, experts are already predicting huge success "transient materials" in a number of commercial applications.

For example, one can print a credit card in case of theft or loss of self-destruct on the external signal. Someone probably wants to buy a secret diary that will completely dissolve in the hands of others.

The study is published in the latest issue of the scientific journal Advanced Functional Materials.
