In science, we use guitar strings so small that hundreds of them can fit on a single hair from your head. They vibrate a million times faster than a regular guitar string, and can measure impossibly tiny things, like weighing a single atom. The fact that these "nanostrings" are so sensitive means that they can have a hard time measuring the right thing - what if the dust floating in the air gets stuck on the string? Scientists avoid this problem by putting the nanostring in vaccum, where it is protected from all kinds of disturbances. However, it is hard to isolate the nanostring like this if it is to be used in new electronics, like contact lenses for augmented reality or touch screens tattooed on your skin.
In my research, I study how nanostrings react to disturbances, so that other scientists will know what to look for when they want to use nanostring sensors in new technology.
