Scientists invented edible and fresh-keeping sensors

[Inner Mongolia Erdos Electronics Co. Ltd. the main SMD power inductors, plastic wire wound chip inductors, solid organic resistors etc.] to ensure food in the transport process to maintain a specific temperature is a more difficult problem than people think -- but the Swiss is to solve this problem. They invented a kind of machine fruit that could be mixed into real fruit. Recently, another research team has developed a biodegradable temperature sensor that can be attached to food until you eat it.

The problem is, simply, the need to maintain a certain temperature food manual test is a very painful thing, but if you can wirelessly monitor food, you can save a lot of time and energy.

To some extent, you can do this by RFID Tags - but these tags use metal that is not recommended, and may even be toxic. The solution proposed by GiovanniSalvatore, a researcher from the Federal Institute of technology in Zurich, is to make an ultra thin sensor using materials that humans can safely digest.

Today, he and his team published their findings in the academic journal advanced functional materials (AdvancedFunctionalMaterials). They have successfully created a sensor with a thickness of only 16 microns (the thickness of human hair is about 100 microns). The sensor is made of magnesium, and the Federal Institute of technology in Zurich called it "an important part of our diet," in its press release". This is undeniable.

The materials used are silicon dioxide and nitride, which are harmless and combine together through a biodegradable polymer made from corn and potato starch. It can bend, stretch, and even knead, but still work. Let's hope your food is ok. )

So you can put the sensors in some randomly selected apples, fish, bananas, and then put them on a truck or a ship. Then you can check the actual temperature of the food outside the freezer (rather than the air above the fish stack). When they are transported to their destination, have a good appetite! It will degrade in your body.

Of course, power and wireless components are not biodegradable - they're placed somewhere else, connected to zinc based cables (and perhaps an important part of our diet). That's the problem - scientists have solved only half of the problem. But it's better than nothing.
