Google is known for its wacky ideas, and the latest patent filed by the firm’s parent company, Alphabet, is no exception.
The patent describes a smart nappy design that notifies parents when their child has gone to the toilet.
The nappy uses moisture sensors, which can even distinguish between wee and poo.
And if the nappy does detect that your child has gone to the toilet, it will send you a smartphone notification that you should change the nappy.
