Human Motion – Chest
Energy Source: Vibration
Application: Human
Specific Location: Front of chest
Data Duration: 6m 40s
Data Frequency: 2048 Hz
Abstract: The volunteer is average height and average weight (180 cm and 82 kg). The data logger was tied to the body using self-adhesive support bandage (7 cm wide, 4 m long) rolled on under tension. The tests were carried out on one of the University gym’s treadmills at three distinct speed settings: slow walk (1 km/h), normal walk (3.5 km/h), and light jogging (6.5 km/h). Data was recorded for approximately 2 minutes at each speed. Potential limitations of the tests include the suspension system of the treadmill, the architectural design of the floor of the gym (allowed to move slightly), and the vibration caused by nearby runners. The tests were carried out in a quiet period, when the usage of the gym equipment was low. The data streams are included in .mat file, titled with the location of each data segments. There are 7 columns of data that represent: time (in seconds), x-axis raw data (in mV), y-axis raw data (in mV), z-axis raw data (in mV), x-axis acceleration (in g), y-axis acceleration (in g), and z-axis acceleration (in g). Starting with 1 km/h, two minutes of data. Next speed is 3.5 km/h (10 seconds switching speed in between), 2 minutes. 6.5 km/h, 15 seconds switch over, 2 minutes of logging, 10-15 s of slow down.
Features:
- 1 km/h: 0 – 124 seconds
- 3.5 km/h: 135 – 266 s
- 6.5 km/h: 272 – 392 s

Started at 2.5 km/h then slowed to 1 km/h, logging for two minutes at this speed. Stepping up to 3.5 km/h, two minutes logged at this speed (around 20 – 25 seconds in between ‘useful’ data sections while adjusting speed). Next speed is at 6.5 km/h, again, two minutes at this speed.
Features:
- 1 km/h: 44 – 176 seconds
- 3.5 km/h: 186 – 310 s
- 6.5 km/h: 328 – 460 s
Human Motion – Hip
Energy Source: Vibration
Application: Human
Specific Location: Just above hip
Data Duration: 7m 02s
Data Frequency: 2048 Hz

Data logger mounted just above the hip. Floor moving was noticeable due to runners on nearby machines but data from data logger placed on treadmill did not reveal any significant background ‘noise’.
Features:
- 1 km/h: 0 – 116.5 seconds
- 3.5 km/h: 124 – 262 s
- 6.5 km/h: 272 – 412 s
Human Motion – Lower Leg
Energy Source: Vibration
Application: Human
Specific Location: Outside of lower leg near ankle
Data Duration: 12m 18s
