What a great teacher aid. You could get AI to identify pupils and have the drone automatically fly round and deliver a cuff around the ears of the culprits.

This is an interesting area of research. Using sound waves to power very small drones could be useful where traditional power sources are difficult to use. It will be interesting to see how further research develops this technology and what practical applications may become possible.
