STMicroelectronics Wearables

Wearable applications are making a growing impact in markets that range from new healthcare technologies including remote heart-rate monitoring to consumer applications such as smart fashion accessories. These applications represent a range of current and future markets that market analysts, Strategy Analytics projects to grow by more than 70% through 2017. STMicroelectronics presents an industry-leading range of motion and environmental sensors and successes in a broad range of already-available wearable applications. New ultra-low power microcontrollers, award-winning BlueNRG Bluetooth Smart wireless connectivity solutions, along side analog and mixed-signal devices from STMicroelectronics provide a comprehensive platform for addressing the needs of any wearable design.



STMicroelectronics Switch ICs

Switches are commonly used to multiplex or de-multiplex a great variety of signals. For instance, in portable applications, switches are used to route signals such as audio to speaker or to headphones. With the sensors and interface proliferation in new applications such as wearables, switches also become the ideal solution to route signals from / towards each other's, and guarantee a simple efficient system implementation.
