Designed to help people better understand their pets, Inupathy measures a dog's heart rate and pulse variations to determine how it's feeling. Starting from US$149 for Indiegogo supporters, the harness is covered in LED lights that change color to reflect a dog's mood. It glows blue when a dog is calm, red when excited, bright white when focused, and shows a rainbow display when the pooch is happy. The data is stored online so an owner can review trends. Inupathy

CEO Joji Yamaguchi was inspired by his Corgi, Akane, who was a nervous puppy. The biologist developed a system to monitor the dog's heart rate and track the dog's reactions to stimulus such as food, games, people and toys. Inupathy
