Wearables

Connected watch

Watches occupy prime human real estate on our wrists. As such they are ideally suited to the benefits of being connected with Bluetooth Low Energy. They can connect to our smartphones and receive message notifications such as sms, email and social media-based. In some cases send back messages also. As with all watches energy efficiency is paramount given the physical limitations in size for batteries. total solution footprint needs to be absolutely minimal and WLCSP packages rule the roost here. Some simpler watches can be single chip designs with a powerful SoC, others may need a simpler connectivity controller to accompany and much bigger application MCU that handles main tasks and interface/display.

nRF52832 SoC bluetooth le/bluetooth low energy bt module — nRF52832

Jewelry

Smart jewelrey combine style and functionality and can come as bracelets, rings and necklaces. They can perform a host of different functions including notifications, activity tracking, heart rate monitoring and access control. These applications are often single chip designs and so need highly capable SoCs with rich peripheral sets and high performance Bluetooth radios. Smart jewelrey has very demanding requirements for compact solution size and need outstanding energy efficiency given the small batteries they must operate from

Proximity tags

Proximity tags have a multitude of uses, but for the most part it comes down to security. Your proximity to something else identifies that it is you and that an action should occur. This can be the unlocking of a computer or door, it can be to adjust a setting to your preference be it the seat in your car or the temperature in a room. Bluetooth Low Energy is the perfect interoprable standard for proximity use cases as it also allows the phone to be a part of the use case. Proximity is fairly simple implementation and with the powerful nRF52 Series SoCs is often an inclusive feature together with other applications that form a product.

Smart clothes and apparel

Wearables also means smart clothing. With today's level of SoC integration and their energy efficiency systems can be sealed in clothing with batteries that will last beyond the lifetime of the article of clothing itself. Others together with solar sources can be self sustaining. These can offer similar use-cases as other wearable devices only stitiched or sealed into the fabric of garments.
