It is possible to create electronic devices, which dissolve, for implantation in the human body, by applying the transient electronics.

A group of researchers from the University of Illinois this week ended in consistent research to develop electronic devices capable of being implanted in the human body and then disbanded once their task ending. The project led by John Rogers of the University of Illinois, has lasted several years during which tests were performed with very different organic and inorganic materials. The objective was that all the electronic components may be eliminated from the body without causing secondary damage.

Electronic components and transient

After endless tests, the materials chosen for the design of the electronic components were magnesium, silicon and silk . Both magnesium as silk do not cause reactions in the organism and can be processed by enzymes, the silicon is chemically inert and melts under the action of water molecules. This development is included within a discipline called transient electronic-purposes to traditional electronics manufacturing materials that are stable and durable.


Other problems

Another of the many problems that scientists found during the development of this project has been the size of the electronic components and the solvency of these within a specified period. The solution has been by way of using nano membranes which can be dissolved in a controlled manner. The factors controlling the rate of dissolution are silk and an interface of an operating system.

Animal testing

Tests, specifically rats have included the subcutaneous implant of a device capable of recognizing bacteria and other microorganisms in wounds, destroying them by applying heat. The desired result was subsequently could dissolve the device on schedule.

Medical Applications

In addition to the application made in this research opens a wide field of applications in medicine.Some of the many examples in which this technology could be applied are as aid to enhance and prevent infection of wounds caused by surgical operations, prosthesis implantation, administration of different types and controlled release of drugs into the body or in the construction of sensors to various body parts such as heart or brain.

Applications in other disciplines

Naturally, developments like this are not limited to one field of application and is already thinking of other possible applications such as the development of new computers and other electronic devices. It is important to consider the contribution that this invention can contribute to reducing waste of all kinds. Just look at the number of phones, radios and electronic components that are thrown away every day can give an idea of the savings that they can be dissolved would. This scientific development has been recently published in the journal Science and is being funded with federal funds from the United States.
