Want to play the piano on your arm?

Technological developments are always throwing up new possibilities, as this video shows.

Scientists have developed a flexible touch pad capable of responding to finger touches, meaning that we could soon be able to play the piano on our arms.

The panel is made mainly from hydrogel and is filled with water. The technology keeps working when expanded to ten times its size. It also has potential benefits for medical treatment, including drug delivery.

The technology is still in the early stages of development and it remains unclear how durable the material is over time. Additionally, it’s currently not always accurate, so don’t get any ideas of holding an impromptu recital just yet!
