Sony has reportedly file a patent application for a ‘SmartWig’.

The firm has said that the SmartWig can be worn in addition to natural hair, and will be able to process data and communicate wirelessly with other external devices.

According to the filing, the SmartWig can help navigate roads and collect information such as blood pressure.

The Japanese firm said the wig could be made from horse hair, human hair, wool, feathers, yak hair, buffalo hair or any kind of synthetic material.

At the same time, the communication interface and sensors placed in the wig are at least partly covered by parts of the wig in order to be hidden from sight during use.

It said that as a result, the device has the potential to become "very popular" as it could be used as a "technically intelligent item and fashion item at the same time".

"The usage of a wig has several advantages that, compared to known wearable computing devices, include a significantly increased user comfort and an improved handling of the wearable computing device."

Sony listed various potential uses of the SmartWig in its filing, including helping blind people navigate roads.

It said that a small video camera or a sensor on the wig could help to provide the position and the location of the wearer.

Sony said the SmartWig will be compatible with other devices such as glasses and smartphones
A remote user can then use the images provided and send vibration commands through the network and navigate the wig user manually to a desired destination.

"Although navigation systems based on vibration motors have been widely introduced, a navigation system integrated into a wig… is so far not known," the firm said.

A further potential improvement of the wig may use ultrasound waves to detect objects around a user.
