Sony Patent Points to Magnetic TMR Tech to Fix PS6 Controller Drift
If your PlayStation 5 controller suffers from analog stick drift, Sony may be preparing a fix for the next generation. A recent patent suggests the main controller input hardware for PlayStation 6 could use magnetic sensors built around TMR (Tunnel Magnetoresistance) technology—aimed at reducing drift at the source.
Quick facts
- Patent proposal for PlayStation 6 controller analog sticks
- Switch from current drift-prone analog approach to TMR (Tunnel Magnetoresistance) sensors
- TMR sensors are described as avoiding drift and outperforming Hall Effect magnetic sensors
- Reported benefits include higher precision, longer lifespan, and lower power use
- Patent also mentions a spring-return mechanism and added stabilization structures
Analog stick drift is widely tied to the way traditional sensing hardware performs over time, and the patent frames the issue as something Sony wants to address with a different sensor layer. Instead of relying on magnetic sensing of the Hall Effect type, the proposal highlights TMR sensors for PlayStation 6’s primary controller controls.
The key claim is performance and durability. TMR is presented as not only drift-resistant, but also superior to Hall Effect sensors in accuracy, service life, and power consumption. Those traits are positioned as particularly relevant for wireless controllers, where efficiency and long-term stability matter.
Why TMR is a focus for wireless pads
The patent notes that TMR-based sensing is already used by some third-party controllers in the mid-to-low market segment. The implication is practical: the technology is described as cost-effective and technically advantageous, which makes it a credible candidate for a large manufacturer looking to improve reliability.
Beyond the sensor change, the document also references additional controller design elements. It includes a spring-return system intended to help center the stick precisely, and “stabilization structures” aimed at improving both accuracy and longevity.
Overall, the patent details point toward Sony evaluating fixes for the most common PS5 pad pain point—drift—while also tightening control feel through mechanical centering and added stabilization. Separate rumors also suggest the PlayStation 6 controller could be modular and include a touchscreen, though the TMR sensor idea is the most concrete hardware-specific direction described here.
