Do you still remember those days when you could go for at least three days without having to worry about how much battery juice you still had on your mobile phone? I do, but the memory is quickly fading. Anyone with a smartphone has probably lamented, at least once, about how often he or she has to plug it in. I know people who do not last half a day without having to resort to an additional battery pack.
It sure is a “first world problem”, but having a smartphone really does make you overly concerned about having access to power. Otherwise, you’ll just have a brick in your hands.
Unsurprisingly, scientists have been looking at ways to provide solutions that will be as convenient as possible. One of these is the result of the work of some guys at Wake Forest University.
