Put and Gone

 Imagine having the ability to create and put electronic devices in your body that simply disappear within a few days. What about medical supplies or a health meter that provide information about your organism, or a small camera to have an endoscopy; there is no need of surgery or using bothering tubes through your body, just use degradable devices. 

   Scientist have developed devices using a mixture of silicon, magnesium and silk to build degradable objects; the silk proteins are used to control the lifetime of such devices, it could a day, a month, even a year, when the time has come the silk packing starts to dissolve until it is completely vanished. As an example, think about a temporal pacemaker, there is no need of a second intervention because it would disappear from the body by itself.  

   Using this principle companies could use this mixture to every gadgetry, in order to avoid an overproduction of technological garbage; this will reduce the ecological impact of technological wastes, as simple as "set" the condition for the degradation process to the device and, Puff!  Your device is no longer with you. It would something great to keep our planet clean; think about how many plastics items could simply disappear from streets and dump? Useful, isn’t it?
