Toilet with buttocks, warning of health condition


The complex and ongoing pandemic of the new strain of coronavirus has forced scientists to develop new experimental methods to detect various diseases in the early stages.

Dr. Sanjiv Gambhir from Stanford University, together with his colleagues, is developing a kind of smart toilet that can detect many diseases based on the collection and analysis of stool and urine samples from patients. The research was published in Nature Biomedical Engineering.


This toilet can detect many diseases based on the collection and analysis of stool and urine samples from patients.

"Research on this method we have done over the last 15 years. Although when it comes to this method, many people even laugh because it sounds like an interesting idea but also a little weird." Gambhir explained.

Equipped with cameras and sensors, this smart toilet can analyze waste to assess health status as well as use "buttocks" to identify users.

Researchers at Stanford University have created a toilet that can identify users through "back holes" to monitor and assess health status.

Since the last century, artist Salvador Dalí has ​​discovered an anus who has about 35-37 wrinkles with different shapes similar to fingerprints. It was an idea for Park Seung-min, Stanford University Professor to create this special toilet.

According to The Verge, the research was published in the journal Nature and quickly attracted attention.

The product is designed as a module so it can be mounted on a normal toilet in the house. It is equipped with a camera attached to the Raspberry Pi computer to take pictures of the anus of the person sitting, then analyzes the "butt print" to ensure the data is correctly linked to each individual.

The toilet has an additional camera to take pictures of sitting waste, motion sensors that record urine flow, and medical sensors analyzing waste. Besides taking pictures of "back hole", toilets also have fingerprint sensor to identify users more accurately.

During development, the researchers created a urodynamic algorithm, which included information about the rate of urine flow, the intensity and duration of urination for each person to compare between people. healthy and ill.

Sensors in the toilet can also analyze the amount of white blood cells, the protein level in the urine to see if the person sitting has a disease related to the bladder.

The toilet can also analyze user waste based on the Bristol Stool Form Scale that divides human excreta into 7 categories. Combined with the time of discharge, the toilet can identify constipation or gastrointestinal diseases. After use, all data and images are saved to an encrypted server to ensure user privacy.
