Ex-Xiaomi executive Wang Teng sells a 1,799-yuan sleep ring.

The devices record a person’s 8 sleeping hours for an AI health service.

A ring and a temperature-control bed cover collect the data, and an AI agent turns it into personal advice.

Wang concedes that few sleep products are scientifically validated.

Services are free at first and paid later, and the bed cover ships in December.
