Smart Watches
Smart watches present a unique set of challenges when it comes to design. They offer a feature-set that goes far beyond what is found in traditional watches but come with expectations of a similar form factor. The features offered by the latest smart watches include application and notification syncing with a smartphone, fitness and health monitoring, location service, voice commands, payment and wireless charging. All this needed to be packed in a very small form factor with outstanding performance and long battery life in order to deliver the best user experience.
ST provides a range of solutions to match the needs of the most advanced smart watch designs.
