How High-Resolution Accelerometers Improve Activity and Balance Research Accuracy – Dr. Olli Tikkanen (Pt2)

Physical Activity Researcher

"Why does measurement resolution matter in physical activity research?"
In this episode, Dr. Olli Tikkanen explores the importance of measurement resolution in accelerometer devices and how it impacts research precision. He breaks down the difference between 10-bit, 13-bit, and 16-bit resolution, explaining how higher resolution enables devices to detect smaller changes in movement and orientation. Using examples like Fibion G2, Dr. Tikkanen highlights how high-resolution devices improve sensitivity for micro-movements, posture detection, and balance measurements—key factors for studying fall risks and low-intensity physical activities.

Dr. Tikkanen also emphasizes the role of high-resolution data in machine learning algorithms, showing how better input leads to more accurate predictions in health and physical activity studies. From detecting subtle body sways to high-impact accelerations, this episode demonstrates why precision is essential for reliable research outcomes.
