Make A Wearable Fitness Tracker!


A personal fitness tracking device is a perfect way to help us understand our exercise and health habits so that so that we stick to our fitness regimes. A lot of these smart wearables help in tracking workout, calorie count, heart rate, sleep patterns, step count and other aspects of the health we want to keep watch on. These gadgets often work together with smartphones and health apps to help in staying fit and healthy.

If you want to get your fitness tracker designs started quicker, walk-through these latest and ready-to-use reference designs from the industry built with power-saving, cost, size and accuracy in mind. Each design is equipped with complete design files, bill of materials, user guides, test data, application notes, and other necessary documentation:-

1. NFC-enabled Smart Patch For Fitness Monitoring:

TI offers a reference design which can measure Electrocardiogram (ECG), Galvanic Skin Response (GSR), skin temperature, heart rate, respiration rate, cadence, step count, and sweet-loss rate. The solution targets applications such as Healthcare, Fitness & Activity Monitors, Wearables and Smart Clothing. The design is both durable and flexible, and adheres to human skin. The design reduces cost and weight using the display of a NFC smartphone to show the measured parameters which are transferred to the phone’s screen through NFC. Dynamic NFC Interface tag supports large file transfer. NFC also reduces power consumption being a low-power alternative to Bluetooth and Bluetooth low energy. The design is battery-powered for continuous monitoring and consumes ultra-low-power. More on this Reference design
2. Accurate Fitness Monitor For Athletes: 

Freescale has developed an accurate and low-cost activity monitor which can be used by sportsperson, athletes and fitness junkies to monitor their fitness. The design can track calories intake, heart rate, speed and distance. Features include USB, graphical display, timer, chronometer, wireless communication, a Micro SD Card to store biometric data, and capacitive touch sensing interface for user control. The design is based on a MCF51MM256 32-bit MCU and 3-Axis Accelerometer. The MCU offers a cost-optimised design, ultra-low-power operation and high measurement accuracy. More on this Reference Design

3. Tiny Pedometer With 3V battery & Graphical Display: 

Microchip offers a low-cost, low-power, wearable pedometer with on-board LED display. Powered by a 3V battery, it can be worn on the wrist like a bracelet or a watch. The design can communicate with a smartphone or tablet using Bluetooth Low Energy. More on this Reference Design 

4. Wearable Activity Tracker With 8-week Battery Life:

ST and ARM have developed a design which can implement activity trackers, wearable healthcare devices, smart watches, wrist-mounted communication devices and more. The design is provided in wristwatch format but readily adaptable to other form factors, such as embedded wearables in clothing. To minimise size, the design utilises ARM Cortex-M processors and the mbed OS. Further, the design is ultra energy-efficient and offers 8-week long battery life. Capacitive touch sensors and tactile buttons are provided to receive inputs. Other important features include modularity which helps include or exclude features as needed, and configurability for additional functionality. More on this Reference design
