Sony has filed a patent application for "SmartWig", as firms jostle for the lead in the wearable technology sector.
It says 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.
Google and Samsung are among the firms that have launched products in wearable technology - seen as a key growth area.
"Wearable gadgets are definitely going to be one of the big areas of growth over the next two years," Andrew Milroy, an analyst with consulting firm Frost & Sullivan, told the BBC.
"And Sony - which is trying to regain some of the sheen it has lost in recent years - clearly understands that and wants to play a major role in the sector."
