Two robots that warn users if they suffer from bad body odour have been unveiled in Japan. One resembles a woman's head and ranks the operator's breath, declaring an "emergency" if it falls into the worst category. The other looks like a dog and growls when confronted with stinky feet.
A Dutch company, Enose, is developing Aeonose, a smell-based diagnostic kit designed to help screen for tuberculosis, asthma and throat cancer. The US-based lpha Szsenszor is working on equipment to study human breath to detect lung cancers and other diseases.
