Wearable is one of the most promising fields of electronics because it offers the possibility to integrate many smart ICs like microcontrollers, motion/pressure sensors, GPS modules into the clothes or watches of the user giving him the freedom to be connected and monitored at the same time: this can be done by checking many important physical parameters like the hearth rate during the daily activities and tracking the position of the user by a GPS in real time. A good example of this type of application is the new multi-sport GPS watches Fenix 6 series, which presents the valuable option of solar energy recharge (Figure 1)
Garmin’s new Fenix 6 series of multi-sport GPS watches is here. The lineup features the first Garmin watch with a transparent solar charging lens, larger 1.4-inch sunlight readable displays, and new features that can extend battery life and more accurately track your performance. These are the watches you buy when outdoor fitness is your priority, money is no object, and adaptability to everyday life indoors is still important. The Fenix 6X Pro Solar is the flagship device. Its “Power Glass” solar lens not only extends the watch’s 21-day battery life (in smartwatch mode) by up to three days, its display is also 36-percent larger than the largest display available in the Fenix 5 series. The solar option is only available with the larger 51mm case, however. Battery life on the 6X Pro Solar model plummets when used in always-on GPS and music mode, of course, dropping to about 15 hours with solar extending life by another hour or so. Life can be extended to 80 days in the battery-saver watch mode, with the solar lens adding another 40 days for a 120-day lifespan before needing a recharge. … . On the software side, the two biggest changes since the Fenix 5 series are a new PacePro feature and more customizable power management. Garmin calls PacePro a first-of-its-kind feature that adapts for elevation changes to keep a runner’s pacing on track. The new Power Manager provides insight into how different settings and sensors affect the power draw, allowing users to disable certain features on-the-fly to maximize battery life.

Such a multi-sport GPS watch needs to be powered with smart integrated circuits, who’s effectively working and reliability is a key factor for the success of this type of wearable solution: indeed, many big electronics companies like as an example, the STMicroelectronics Company, are producing many ICs (microcontrollers, accelerometers, …) suitable for wearable solutions (Figure 2).
When people think of harvesting data, they think of wearables or other personal products, but their communication capabilities are often basic. Connected X.0™, from the American design and engineering consultancy Nytec Inc., is a platform of technologies that come together in the form of a wearable and set of aggregator sensors. It integrates a LIS2DH12 accelerometer and relies on a smart communication system, the aggregator, that embarks an STM32F4 microcontroller. The first deployed solution is changing the hospitality industry with its ability to track people and things on property, provide secure access to doors and gates, and deliver unified payments. Connected X.0 also serves as a platform that Nytec can customize for their clients to adapt it to a wide range of applications, across oil and gas, stadiums, micro cities, smart business campuses, equipment monitoring/tracking for smart factories, and more.” (Source: ST Blog)
