A new smart pillow has appeared - it monitors the quality of sleep and is charged from head movements.

A smart pillow, or rather a set of fitness trackers, is suitable for normal sleep, preventing falls from the bed and monitoring people with neck diseases. During the experiments, the pillow calculated the pressure distribution of the head of a restless sleeping person. Also, the system was able to track the movement of the finger with which the letters were drawn - that is, it is very sensitive.
