German scientists have engineered a device that would allow your shirt to come up with a message, “Don’t you think you’re taking things over the top. Just take a stress pill or go for a massage therapy!” This is a close contingency as they’ve developed a new sensor that detects muscle excitation and stress. Apparently it’s flexible enough to be woven into clothing and survives washing too. (Can you afford one for each piece of clothing?) This is particularly helpful for sports training, where coaches will have an exact idea as to when the athletes have to be drilled and when they can take a break. The special vest even lets you control your games console.
