The Nintendo key may be remembered at the same amount to re -create mobile games as much as it will affect millions of players: Drinking control stick.
The drift is the most common term for a problem where the control stick discovers false inputs – even when no one touches a console – causing unwanted movements in the game. The case also affects the control units of Sony, Microsoft and Threed Thcktory.
Hall effect sensors A few years ago, it appeared as a possible solution to the problem, but there is a better option that is easier to re -modify the current control unit designs. This solution is the magnetic resistance of the tunnel, or TMR, a technique that revolutionized the steel driving two decades ago using quantum and magnetic mechanics.
Like the hall effects, TMR sensors avoid the basic problem with more traditional control stick: its sensors wear them as a design issue. Control units that are shipped with the past few keyboards are built Xbox, PS4 and PS5 and the key around these sensors such – voltage standards, a component that can be used to change or measure electrical resistance.
Solid organisms that rubbed against each other is not an ideal way for longevity
like Ifixit explained in 2021Inside the voltage standards that are used to discover the movements up, down and side in each control stick, it is a semi -circular strip of the carbon movie with ends on each side that passes an electric current through it. When moving the control stick, a component called a wiped molded and forth slides along this tape, and measures the voltage where it connects. Since the voltage changes expected across the tape, voltage measurements of spaces can be used to accurately measure the control stick.
But the hard things they rub against each other are not an ideal way for longevity. This ribbon can rise from the carbon film within the voltage scale in the control stick over time, affecting the flow of current and the accuracy of the voltage measurements. Dirt can contribute to the film, either from moving ingredients that we wear or find dust and food on its way within the control unit, in an inaccurate measurement and erosion.
For this reason, the console manufacturers now turn into not dependent on the components that are rubbed together: Hall Effect and TMR, both of which depend on magnetism instead. like Ifixit explainsThe Hall Effect control stick replaces the resistant and wiped strips of the magnet and the sensors that never connect, using a phenomenon discovered by Edwin Hall for the first time in 1879.
Inside a hall effect sensor, there is a connected material called the “component of the hall” through which it flows. Usually, electrons flow directly through this conductor, but the presence of a magnetic field can interfere in electrons and convert them to either side, such as an invisible obstacle to convert water flow in a stream. As the magnet associated with the control stick approaches, the hall’s effect senses measure the voltage changes in the conductor. These measurements are translated into movements in a more accurate and reliable game than you get with voltage standards, and without any erosion.
The hall’s effect sensors were used for more than 50 years-and SEGA used it in Saturn 3D and Dreamcast units that first appeared in the mid-1990s. Ghulikit is re -used Hall effect sensors in gaming devices After the appearance of a controller with it at E3 2021, but it is still widely used in gaming devices because the voltage control stick is cheaper for manufacturing. They also have higher energy requirements, something that needs to be controlled.
What makes the TMR effect useful on electronics is not the tunnel itself
The solution may be TMR sensors, which come out of the most modern discoveries. In 1988, physicists Albert Volt and Peter Genberg independently discovered a phenomenon called the GMR resistance effect, which was received by the Nobel Prize for Physics in 2007. They found that the presence of a magnetic field applies to nearly its character, just as there were a few of the common field. It would affect the direction of electrons and their ability to flow easily from one side to the other.
“If you put two magnets next to each other … very close to each other with a separation material, if the magnet has this one that rotates a and in Spin is on the other, it is easy for electrons to move to the next story. But if others have an unspecified rotation, then the electrons want to move, but there is no easy way to move the other electrons, preferably, and they benefit from an amount of pre -resistance. Seagate, explain to freedom.
TMR works very similar to GMR. The presence of a magnetic field increases the direction of rotation of the electrons, which makes it easier for them to flow from one side to another. But while GMR uses a connected material between two magnetic layers, TMR, contrary to a buffer material that works as a deliberate barrier.
For one side of the movie to the other, the electrons depend on a quantum mechanical phenomenon called the quantum tunnel to pass it between the insulation. The idea of particles that pass through a barrier should not be able to wrap your head around it, but this can happen when some materials – such as aluminum or magnesium oxide – just a few atoms. Thanks to the physicists such as Erwin Schrodinger, the phenomenon is not a complete mystery. We have equations that can accurately predict the date of their occurrence.
What makes the TMR effect useful on electronics is not the tunnel itself. Adding and removing a magnetic field produces a tangible change in the resistance. For years, hard drives have relied on reading heads with a design similar to wire files used in loudspeakers and microphones, according to Mendonsa. In 2005, Seagate adopted TMR technology in reading heads, which could not only be much smaller, but was also much more sensitive to discovering the existence of a magnetic field.
“TMR sensors generally have a higher sensitivity and linear response compared to the hall effect devices.”
This allowed the manufacture of magnetic parts on hard drives, which greatly increases the density and storage capabilities of 2.5 inches to 120 GB. Various forms of TMR technology are expected to be used in the manufacture of the hard drive for years to come.
Although the basic science is different, Hall Effect and TMR sensors can be used to detect control stick movements by using non -contact magnets, but TMR sensors have some major advantages.
“The TMR sensors generally have a higher allergy and linear response compared to the hall effects,” says Jack Hu, Gulikit business manager. This can be allowed to use a smaller magnet, making the TMR manufacturing manufacturing easier. But taking advantage of the high sensitivity to improve the accuracy of the control stick will depend on the manufacturers and the devices they use. “The decision depends mainly on the accuracy of the samples of the MCU background, and it is not closely related to the same control.”
Compared to the hall effects, the TMR sensors usually have less power consumption devices, but the feature has not been improved battery life. “The original design of the Sony, Microsoft and Nintendo control device is used by resistant films with a continuous design for energy saving, with energy capacity limited to about 1 mA.” The hall sensors can be consumed anywhere from 0.5ma to 2MA of energy, while TMR sensors only consume between 0.1MA and 0.3MA. This allows control clips with TMR sensors on the current control unit “as a perfect alternative 1: 1 without any other circle modifications.” This can help accelerate the adoption and reduce the price of technology by simplifying manufacturing.
TMR sensors also provides more performance stability – a specially useful feature of the product that is often caught with warm hands for several hours.
Although TMR technology has not yet been adopted by companies such as Nintendo, Microsoft and Sony, there are many manufacturers to foreign bodies that already sell games games with TMR, including PB Tails’ Crush Controllerand Gamesir’s Tarantula ProAnd 8bitDo, which it uses in New Ultimate 2 control unit. In 2024, Ghulikit was the first company Launching promotion sets that brings TMR technology To PS5, PS4, Xbox and Switch Controlers.
But a few years will remain to become TMR technology prevailing in gaming devices. “TMR sensors are often more expensive than traditional hall sensors, especially in smaller sizes,” he indicates. “However, with the maturity of TMR technology, the cost difference is expected to decrease.”
