Mirai Create Unveils Battery-Free, Sensor-Free EMR Gaming Mouse

A new era for wireless gaming mice is on the horizon with the upcoming reveal of a revolutionary device at the Tokyo Game Show 2025. This pioneering mouse eliminates the need for both internal batteries and traditional optical sensors, instead harnessing electromagnetic resonance (EMR) technology for seamless operation. This advancement could lead to significantly lighter peripherals, offering an unparalleled user experience without the inconvenience of charging or battery replacement, while also opening doors for novel control mechanisms.

Conventional wired mice typically require no power source beyond their connection, while most wireless models rely on internal batteries, often necessitating regular recharging. Mirai Create's innovative Super EMR Mouse challenges these norms by employing a unique approach to both power delivery and motion tracking. This technology, drawing parallels to Wacom's pen and digitizer pads, enables the mouse to function entirely without onboard power, drawing all necessary energy and positional data from a specialized mat.

The core of the EMR system involves a pad containing a grid of resonant circuits, each comprising a capacitor and an inductor coil. When an electrical charge is introduced, these circuits resonate at a specific frequency. This resonant energy is then wirelessly transferred to a corresponding inductor coil within the mouse through a process known as mutual induction. The strength of this induced signal directly correlates with the distance between the mouse's coil and the pad's circuits. By strategically arranging these circuits for both horizontal (X) and vertical (Y) axes, the system achieves highly precise tracking capabilities.

Beyond basic movement, this EMR technology also offers intriguing possibilities for enhanced control. The system can detect additional axes of movement, such as tilt and twist, opening up potential for advanced in-game functionalities like leaning in first-person shooters. While the Mirai Create Super EMR Mouse's full capabilities in this regard are yet to be detailed, the inherent design of EMR allows for such sophisticated input, depending on software integration and game support.

One notable advantage of this battery-free design is the potential for an extremely lightweight mouse, enhancing comfort and reducing fatigue during extended use. Furthermore, the absence of an optical sensor eliminates concerns about surface compatibility, as tracking is entirely managed by the EMR pad. However, this also presents a limitation: the mouse's functionality is strictly tied to its accompanying pad, restricting its portability compared to conventional wireless mice that operate on various surfaces.

While full specifications, including weight, pricing, and availability, are still under wraps, Mirai Create's Super EMR Mouse promises to be a significant leap in peripheral technology. With a reported 1,000 Hz polling rate and an impressive 0.01 mm resolution, this innovation could redefine expectations for wireless input devices, particularly for dedicated gamers seeking the ultimate combination of precision, lightness, and freedom from battery constraints.
