We were hoping for flying cars, hover boots and robots that do the housework. However the future has brought us the texting underpants. OK, it’s more serious than that because they have a genuine use. An Australian company called SIMSystem have come up with a sensor which can be worn by the elderly which can alert carers by SMS should they have an incontinence problem. It’s not a particularly pleasant thing for either carer or the elderly themselves, but it is good to see technology doing something that can help improve the quality of life in that area.
