Intelligent toaster and a ‘nappy fullness sensor’ among UK inventions in 2021

Other inventions include a humane insect remover, a gas-flushing toilet and a collar that stops dogs fighting

An artificial intelligence-driven toaster that gets the perfect level of brownness each time, a device to humanely remove flying insects from a room, and a sensor that tells you when a nappy needs changing. These were just three of the new things created by UK based inventors last year.

A Guardian analysis of patent applications listed by the Intellectual Property Office (IPO) found 6,087 patent applications published with at least one UK-based inventor listed in 2021.
