Sony seeks “SmartWig” patent for hairpieces with sensors

We’re all familiar with the smart watches and smart glasses that make up the frontier of wearable tech, but what about a smart wig? Bloomberg says Sony (s adr) has filed a patent for a “SmartWig,” which could do anything from play music to check the blood pressure of the wearer. The wig could also have a built-in camera, laser, or even a GPS sensor. There are even prototypes in the works, suggesting that Sony is interested in taking this kooky concept to reality.
