Described is a method to detect an analyte in an analytical toilet that includes the steps of receiving excreta in a bowl, transporting a measured sample of the excreta through a passage and bringing the sample into contact with a sensor. The sensor comprises a FET configured to interact with an analyte in the excreta. When the sample is brought into contact with the sensor, the sensor indicates the presence of the analyte by a distinct electric signal.

A reactive treatment formulation and method for treatment of waste material resulting in a more stable, entombed treated waste product. The formulation comprised of a foamable surfactant that is granular and sodium percarbonate. A multi-part formulation can be delivered in a multi-compartment vessel that cooperates with a dispensing mechanism for a self-contained non-contact agitating toilet. The reactive treatment formulation prevents odors, bacterial growth, and stabilizes waste to reduce spillage during disposal.

An in-toilet urine sampling and measurement system is disclosed. One or more toilet sensors trigger volatilization, measurement, and analysis of volatile compounds in a urine sample. Volatile urine compounds may be concentrated, measured, and analyzed by a measurement system attached to a toilet bowl. A volatilizer system may use heat generated from one or more measurement devices to assist in volatilization of the urine sample.

A an analytical toilet comprising a bowl for receiving excreta comprising a platform for receiving feces; a urine drain; a feces outlet from the bowl; and a urine outlet from the bowl; wherein the platform and drain are separated by a raised hump; at least one first load cell for detecting the weight of the bowl; at least one fecal sensor for detecting at least one property of the feces; and at least one urine sensor for detecting at least one property of the urine is disclosed.

Provided is a urine-feces separation toilet bowl including a urine and feces separator configured to separate urine and feces and use them to generate renewable energy. The urine-feces separation toilet bowl includes: a main body portion configured to accommodate excreta; a cover portion having a plate shape, having a first surface and a second surface, and provided on the main body portion, the first surface being arranged towards the inside of the main body portion; a toilet seat portion between the main body portion and the cover portion; an excreta accommodation portion including a first accommodation portion configured to accommodate urine and a second accommodation portion configured to accommodate feces; and an excreta separator between the first accommodation portion and the second accommodation portion and configured to separate the first accommodation portion and the second accommodation portion.

A smart toilet comprising a bowl for receiving; and a projector adapted to display images or data onto the bowl is disclosed. The projector may display images, colors, or information including health and wellness information about a user or about the status of the toilet system.

An analytical toilet comprising: a bowl for collecting feces from a user; a comminutor that comminutes at least a portion of the feces; a processing fluid driver that causes a processing fluid to mix with and transport at least a portion of the comminuted feces to an analytical station in the toilet; a separator that separates a sample of the at least a portion of the comminuted feces to be analyzed; and a wash fluid driver that causes a wash fluid to wash the feces out of the bowl.
