Sony has patented a system that would allow PlayStation controllers to recharge using solar energy, storing generated electricity for later use, according to a report from Tech4gamers.
The patent, described as an “operation device,” outlines the integration of photovoltaic elements into a controller’s design. These photovoltaic units would convert light into electricity and charge an internal battery so the controller could replenish its power when exposed to light without relying on external chargers or disposable batteries.
How the solar charging would work
The disclosed technology centers on basic photovoltaic components embedded in the controller. Electricity produced by those elements would be routed into on-board storage, enabling the device to charge itself while in illuminated environments.
In practical terms, that means controllers using this system could reduce dependence on traditional charging methods and on replaceable batteries, which currently must be swapped or recharged when depleted.
Commercial rollout not guaranteed
Sony has not announced any plans to bring the solar-charging controller to market. The company would reportedly consider introducing the feature in a new controller line only if it can demonstrate that solar charging is commercially viable.
Context: ongoing controller innovations
The solar-charging patent is one of several recent Sony filings focused on controller features. Past patents have explored ways to change a controller’s temperature in response to gameplay and to use electrically responsive inks to let players customize layouts that adapt to their play style, as reported by Exputer.
Another patent mentioned a so-called “anti-fatigue” button that would register a single press and release while the system treats the input as continuously pressed, reducing repetitive strain for users.
