It’s not really hard to believe that how much can be achieved due to the recent progress of science in the area of 3D printing; these great accomplishments have come about in short periods of time. This time 3D printing brings us something really unique, scientists have finally established that functional electrical components can be made using 3D printing; this includes 3D printed sensors as well. The researchers have made a 3D printed wireless smart cap.
These unique caps will let you know more about your milk
In the US, some researchers from the University of Berkeley California, came up with a demonstration of a 3D printed wireless smart cap, specifically designed for milk bottles. This smart cap is used to inform the consumers whether the milk they are going to use is fresh or not by using the sensors embedded in the cap that detect whether there’s anything wrong in the milk, because it’s better to know before making a cup of tea rather than drinking rotten milk. Once these electronic sensors are fitted, all you need to do is to tilt the container upside down in order to check for any changes in the electrical signals being provided by the smart cap.
“This 3D-printing technology could eventually make electronic circuits cheap enough to be added to packaging to provide food safety alerts for consumers”, said Liwei Lin, a senior author on the paper describing the discovery. “You could imagine a scenario where you can use your cellphone to check the freshness of food while it’s still on the store shelves.”
The sensors are specially designed in a way which enables the smart cap to check and detect any abrupt or even slight changes in the milk which then make changes in the electrical signals due to increased levels of bacteria in the milk. Since it transmits the details in real time, this certainly explains how you can now check the freshness of food even before you buy it and specially before using it.
“Our paper describes the first demonstration of 3D printing for working basic electrical components, as well as a working wireless sensor,” said Liwei Lin, senior author of the study, in a press release. “One day, people may simply download 3D-printing files from the Internet with customised shapes and colors and print out useful devices at home.”
The same researcher’s lab is also working for other potential health applications that can further improve the living standards, including those which can monitor high or extremely low blood pressures, muscle strain or applications of similar sort and nature.
