An adaptive transmission algorithm for an inertial motion capture system in the aspect of energy saving

The article presents a tested, integrated architecture of a single sensor network node with an algorithm that has allowed to reduce power consumption, without limiting the ability to process data from a multi-axis MEMS sensor. In the experiment described in the article, the energy efficiency of the sensor module has been increased by 64%. By using the SoC chip system, the printed circuits (PCB) of the sensor module have been reduced to 26 mm × 16 mm. In turn, the use of the Modem Sleep mechanism has allowed for effective feeding of the developed sensor module by means of a battery with 175 mAh capacity whose dimensions do not exceed the size of PCB.
