The MPR084EJR2, is a touch sensing module from the MPR-084 series from Panasonic\'s adaptive antenna touch family. This module contains a controller IC and four independent conductive copper analog resistors. The MPR084EJR2 is most commonly used in haptic feedback applications, industrial and medical equipment, gaming controllers, wearables and automotive user interfaces. It has the capabilities of both a technology and a type of sensor.

The technology used in the MPR084EJR2 is an adaptive antenna touch technology, which is based on the principle of capacitive sensing. This application works by detecting a change in the capacitance of an element when it comes in contact with a conductive object. The four independent conductive copper analog resistors act as the electrodes, while the touch sensing module contains a controller IC that interprets the changes in capacitance. This controller IC processes the raw data from the analog resistors and calculates the relative capacitance for each electrode. The capacitance detected by each electrode is compared to a set value and based on this comparison, the controller IC generates an interrupt that can be used to indicate a touch.

The MPR084EJR2 is most commonly used in haptic feedback applications, industrial and medical equipment, gaming controllers, wearables and automotive user interfaces. It provides an efficient way to sense a user’s touch, while also providing an enhanced user experience. Haptic feedback applications require precise control and the ability to quickly respond to a user’s touch. The MPR084EJR2 is capable of sensing a user’s touch at speeds of up to 40 mHz, which is more than enough for most haptic feedback applications. In addition, the MPR084EJR2 has the ability to distinguish between different touch locations, allowing for more precise control. For medical and industrial equipment, the MPR084EJR2 provides both accuracy and precision when taking measurements.

The MPR084EJR2 also has the ability to recognize different types of touch gestures. For gaming controllers, this allows for more advanced interaction with games, as users can now interact with more precise movements and more precise controls. For wearables, the MPR084EJR2 can recognize different hand gestures, which allows for more intuitive control. In addition, the MPR084EJR2 is capable of recognizing multiple point touches, which means it can recognize when multiple fingers are pressed against the electrodes at the same time.

The MPR084EJR2 is a very versatile touch sensing module, capable of providing an enhanced user experience in a wide range of applications. With its precise control and quick response times, it is ideal for haptic feedback applications, industrial and medical equipment, gaming controllers, wearables and automotive user interfaces. Its ability to recognize different types of touch gestures and multiple point presses make it a great choice for applications that require a precise sense of touch.
