March 29: according to foreign media reports, Apple has applied for a patent for a mattress sensor, which can monitor people's sleep and act as a silent alarm clock.
The patent, originally filed on September 14, 2020, but not released until March 25, 2021, outlines a new sleep related system that allows a control device to provide tactile feedback on a mattress.
In addition to this patent, Apple has demonstrated its sleep related ambitions through other patents, including a patent for a sleep tracking system. In 2020, the company introduced sleep tracking into the apple watch.
In 2017, apple acquired beddit, a Finnish bed sensor company, which uses a mattress sensor to detect sleep patterns.
