### PRESS RELEASE ###
E-bikes are about to get safer and more fun to ride thanks to improved sensor technology from Danish Sensitivus Gauge. The perfect e-bike feels like any other bike, only you are much stronger. The natural bike feeling requires zero lag between what happens at the pedals and what happens at the motor. Integrating a fast torque/cadence sensor solves that problem.
Coming out of power meter development, Sensitivus is introducing a new technology for combined torque and cadence sensors to make riding e-bikes more natural and thus much safer and fun.
Sensitivus new torque sensor technology
“Our solution is an improved strain-gauge based torque/cadence sensor with great accuracy and virtually zero lag”, explains Sensitivus’ CEO Rolf Ostergaard. “The torque sensor completely changes the ride-feel. This faster and more natural link between pedals and motor improves safety and rider experience at the same time”, continues Ostergaard.
This new technology for accurate, reliable, low-latency torque-sensing, is getting integrated into several e-bike systems with the first systems already shipping.
New torque sensor advantages
The contactless torque sensor is customized for each unique application and design. By customizing the shape of the sensor, the integration is optimized to utilize the space available. Typical applications for the sensor are in mid- and hub-drive configurations.
This innovative torque sensor technology combines strain gauges with contactless power and data transfer and is significantly more accurate (1-2%) and faster (5-10 ms) than previous generation products.
An integrated fast-response cadence sensor complements the system initially with up to 64 steps resolution.
Reliability is a great concern for electronics on bikes and a lot has been learned from the automotive industry in similar harsh environments. Sensitivus offers all torque sensor customizations using automotive grade components (AEC-Q).
Sensitivus will be available for meetings at Eurobike in Friedrichshafen, Germany from the 1st to the 4th of September 2021 where the first e-bikes using the technology are also on show.
