ROHM developed the acceleration sensor "KX126" with built-in walking detection and step counting function

Thursday, July 19, 2018

Helps miniaturization and low power consumption of smartphones and wearable devices.

Kionix, Inc., a subsidiary of the ROHM Group (headquartered in Ithaca, NY), developed the 3-axis accelerometer "KX126", which is ideal for pedometer functions on smartphones and wearable devices.

This product has built-in walking detection and counting algorithm in the sensor, no need to design the circuit separately for the pedometer function, which helps to reduce the design burden of the customer. In addition, with the optimized ROHM's unique low-power algorithm, the new pedometer function requires only 100nA, which contributes to the low power consumption of the application (the normal acceleration sensor consumes about 150uA). Not only that, but in a small 2x2x0.9mm package, the pedometer function can be realized even in a limited space.

In recent years, in the field of fitness, the demand for a higher-precision pedometer that is equipped with a walking detection function for detecting a walking state and a step counting function for calculating a number of steps is increasing. This advanced pedometer is also expected to showcase its expertise in the field of care, logistics and workplace productivity.

In addition, the number of such sensors-equipped applications has increased year by year, and at the same time, there are more and more products such as algorithms built into the sensors. By incorporating various functions directly into the sensor, it not only provides an easy-to-use product, but also helps reduce battery power consumption and miniaturize applications.

In this context, Kionix has developed a high-performance, low-power 3-axis accelerometer with a built-in pedometer function in a small 2x2x0.9mm package and expanded its product lineup with its MEMS technology.

The newly developed KX126 also inherits the advantages of the Kionix accelerometer that has been accumulated for many years.
