Case Study: Brazil’s Industrial Smart Bracelet


In this real-world example, we partnered with a customer from Brazil who had specific requirements for an industrial-grade smart bracelet. They needed a smart bracelet with an easily removable strap and, more importantly, unmatched quality and accuracy in sensors.

Customer Challenge:

The Brazil customer had previously tested consumer-grade smartwatches but found that the quality and accuracy of the PPG (Photoplethysmography) and acceleration sensors fell short of their needs. They were on the lookout for a high-accuracy smart bracelet that could provide the best PPG and G-sensor quality to kickstart their project.

Customization Goals:

The customer from Brazil had a highly capable development team proficient in communication protocols, algorithms, AI, firmware, and software. They aimed to leverage our semi-finished hardware to develop their firmware and integrate their proprietary algorithm into the hardware.
