Abstract

This paper introduces the new design of a Micro Inertial Measurement Unit (μ-IMU)-based sensor mote for wireless body sensor network (BSN). The μ-IMU unit consists of a three-axis accelerometer, a three-axis gyroscope MPU6050, and a three-axis electronic compass AK8975. The MCU uses a CC2530 which integrates an 8051 core and 2.4GHz RF. The hardware design and Z-Stack-based software architecture of the sensor mote are discussed in details. A MATLAB program is used to collect experimental data for verification. This system shows several advantages in high integration, compact volume, and accurate sensing capability, which is critical for wearable inertial measurement and body capture.
