Ever wanted to wear a wig but just couldn't find the right excuse? The Sony smart wig, for which the company recently filed a patent, could be your savior.

Made from "horse hair, human hair, wool, feathers, yak hair, buffalo hair or any kind of synthetic material," according to Sony, the hairpiece currently has three different prototypes: Presentation Wig, Navigation Wig, and Sensing Wig, Bloomberg reported.

The names are all self-explanatory of their functions, according to Bloomberg. From Presentation Wig come a laser pointer and the ability to change Power Point slides. Navigation Wig uses GPS and directs its wearer left or fight via vibrations. Sensing Wig provides biological information such as temperature and blood pressure.

"It is an object to provide an improved wearable computing device," Sony said in the patent application.

Will it pass as a wig or resmemble a hair-tech hybrid a la "Predators?" According to the patent, the technological features will be hidden.

"At least one sensor, the processing unit and the communication interface are arranged in the wig and at least partly covered by the wig in order to be visually hidden during use," Sony confirmed in its patent.

Mitsushige Akino, chief fund manager at Ichiyoshi Asset Management Co. in Tokyo, praised the design, but was unsure of its appeal to a mass audience

"It's an interesting idea but I think it would be very difficult for Sony to commercialize," Akino told Bloomberg. "Who will want to use this wig will become a problem."

Sony spokesperson Saori Takahashi confirmed Akino's concerns in a phone call with Bloomberg. "It has not been decided whether to commercialize the technology or not," he said. "The research process is continuing."

If current wearable technology trends hold, Saori should commercialize and Akino may regret his words. Juniper Research predicts the market for products like Google Glass and Smart Watches to increase to $19 billion in the next five years, according to Bloomberg.

"Smartwatches are already made by many companies, so this is something new and fun," said Junya Ayada, a Tokyo-based analyst at Daiwa Securities Group Inc.

Sony filed over 3,000 patents in 2012 -- more than Microsoft and General Electric and less than International Business Machines Corp., Samsung and Canon Inc., according to Bloomberg.
