RUNEASI GUIDE · THE BELT
The Runeasi belt and sensor.
One small sensor in a neoprene belt, with no cables to plug in.
THE SHORT ANSWER
What is the Runeasi sensor?
It is a small motion sensor, 36.6 mm (1.44 in) across and 10.6 mm (0.42 in) thick, that weighs 9.4 g (0.33 oz) with its battery. It takes 1,000 readings a second, handles impacts up to 16 times the pull of gravity, and sends data by Bluetooth 5.0. A neoprene belt holds it at your waist.
Runeasi's booklet describes the sensor and belt in detail. These are its figures.

THE SENSOR
A small, precise motion sensor.
The sensor measures acceleration: how fast your movement speeds up or slows down. It can measure up to 16 g, which is 16 times the pull of gravity, and it takes 1,000 readings every second. Runeasi says this range and speed capture the full range of running movement and are needed to measure the forces involved.
It is slim and light: 9.4 g (0.33 oz) with the battery, 36.6 mm (1.44 in) across and 10.6 mm (0.42 in) thick, small enough to sit close to the body.
BUILT FOR RUNNING
Water and shock proof.
The sensor is built for hard training and sweat, and for running outside in rain or sun. It is made to take the repeated impact of running.
POWER
No charging, no wires.
A replaceable coin-cell battery powers the sensor for up to months, depending on how much it is used. Data goes to the app by Bluetooth 5.0, live during the run or after the session.
THE BELT
A belt that holds the sensor still.
The belt holds the one sensor, and it goes on and off in under 30 seconds. Anti-slip neoprene keeps it comfortable on the skin and keeps the sensor in the same place for the whole run, so the readings come from your movement alone.
The sensor sits upright at the centre of the lower back for whole-body and pelvis data, or flat across the pelvis for separate left and right leg data.

FAQ
Common questions.
Runeasi's method rests on one validated sensor that tracks the acceleration of your body's centre of mass. The research behind it set out to give these insights without an expensive indoor motion lab.
Yes. Runeasi's jump screening uses the same belt and sensor to measure jump landing and jump performance, on two legs or on one.
Runeasi lists remote testing among its uses, and the sensor is built for outdoor running. Ask the New Westminster studio what fits your plan.
