Its 13-bit resolution (4 mg/LSB) allows pedometers to even measure low-speed walking (where each step represents about 55 mg of acceleration change) with reasonable accuracy.
The ADX元45's proprietary (patent pending), on-chip, 32-level first-in, first-out (FIFO) buffer can store data and operate on it for pedometer applications to minimize host processor intervention, thus saving system power-a big concern for portable devices. This article, based on a study of the characteristics of each step a person takes, describes a reference design using the 3-axis ADX元45 accelerometer in a full-featured pedometer that can recognize and count steps, as well as measure distance, speed, and-to an extent- calories burned. The small, thin, low-power ADX元35, ADX元45, and ADX元46 3-axis accelerometers from Analog Devices are very suitable for such applications. Taking advantage of the low cost and minimal space- and power requirements of MEMS inertial sensors, pedometers are being integrated into an increasing number of portable consumer electronic devices-such as music players and mobile phones.
Today, advanced pedometers rely on microelectromechanical systems (MEMS) inertial sensors and sophisticated software to detect true steps with high probability MEMS inertial sensors permit more accurate detection of steps and fewer false positives. When these devices are shaken, one can hear a metal ball sliding back and forth, or a pendulum striking stops as it swings.
Early designs used a weighted mechanical switch to detect steps, plus a simple counter. Pedometers, now popular as an everyday exercise progress monitor and motivator, can encourage individuals to compete with themselves in getting fit and losing weight.
