This is amazing. I've never heard of this before. I can think of millions of potential applications; make car tires stick to the road when cornering, replace seatbelts with a electric car seat, glasses that stick to your face, a phone that sticks to your ear, shoes without laces. I'm sure I could come up with a lot more ideas too.
