Tests for number 1 and number 2 are being developed and tested to use in smart toilet technology for humans. A paper describing the bathroom device research was recently published in Nature Biomedical Engineering.
The smart toilet automatically sends data extracted from any sample to a secure, cloud-based system for safekeeping. The flush lever uses a fingerprint reader along with a visual scan of the user’s backside orifice to identify the person on the throne.
