Train smarter, swim faster.
At Chaze, our goal is to develop hardware and software that makes swimmers more achieved, more inspired and more connected in the sport we love.
For that, we have developed the Chaze Smart Band, a device that tracks a swimmer’s arm trajectory and applied power. The unique combination of power and motion enables swimmers to visualize their technique and chase their potential. By analyzing the data, beginners have a lower burden to learn new strokes, and professionals can precisely tune their training for maximum results.
Our mission
Swimming is one of the technically most demanding sports. In order to effectively convert power into speed, many factors must work together in perfect harmony. Without good feedback, swimmers cannot reach their full potential. Unfortunately, despite swimming being one of the most popular sports world-wide, good feedback is difficult to find and doesn’t come cheap: Currently, swimmers have the option to either join a club or get private lessons. Both options are costly and don’t fit every swimmer’s desire for flexibility and independence.
Chaze will provide users with an affordable alternative they can use anytime and anywhere. We will both provide feedback on the swimmer's technique and performance: Technical feedback includes the swimmer's arm trajectory, which allows athletes to spot inefficiencies and fine tune their stroke with a precision, that can't be matched by any other method common in the sport. The performance feedback includes metrics like applied power, which lets athletes train at an optimal strain to get the most out of their training efforts.
What’s inside
The inside of the band consists of state-of-the-art technology packed on minimal space. The band’s powerful processor allows it to sample at high rates as well as to sync data over WiFi and Bluetooth. The band also contains two multi-color LEDs and a vibration motor, that provide visual and haptic feedback: If a swimmer swims above or below a desired strain, he is notified and can thus adjust the performance. This lets the swimmer swim at optimal strain and get the most out of the training. The band can store eight hours of swimming data that is sampled from its high-precision motion sensor as well as two pressure sensors.
The band features two custom printed circuit boards (PCBs), one located in the swimmers hand palm and the other located on the back of the hand. To enable communication, the two PCBs are connected with a flexible printed circuit (FPC). The protected lithium-polymer battery is space-efficiently placed below the main PCB inside the swimmers palm curvature.
Fully charged, the band can record four hours of swimming. When the band is not in use, the battery lasts for multiple months thanks to an elegant circuit, that puts the device into an ultra low-power “deep sleep” state.
