Smart Connected Wearable Activity Monitor

Microchip Technology’s ULP (ultra-low-power) connected wearable activity monitor reference design features the SAML21, a high-performance, 32-bit Arm® Cortex®-M0+ microcontroller with ultra-low-power technology, the BTLC1000 4.1 Bluetooth® low energy (BLE) module, the ECC508A CryptoAuthentication™ chip as well as movement and environmental sensor chips. High-end wearable activity trackers can take step count, temperature, light, and other movement and environment measurements. They are not only being used for fitness applications but are becoming an essential part of medical device design. Microchip’s ULP connected, wearable activity monitor demonstration board can be used as the starting point for the design of medical home monitoring, patient tracking, and drug delivery compliance devices.

This reference design is a high-end activity tracker demonstration and development board that not only measures a user’s motion and environment but can also be used as a starting point for the design of more advanced activity and biometric measurement devices. These types of devices measure and analyze sleep quality, heart rate, body temperature, blood oxygen, and more. Bluetooth connectivity allows the demo to communicate with tablets, smartphones, or PCs for IoT capability. The wide breadth of Microchip products makes innovative designs like the ULP connected wearable activity monitor possible for a user’s next medical design.

Features

• Ideal for designs that need medical patient tracking, patient compliance, patient biometric diagnostics, fitness activity tracking, and more
• Measures proximity, step count, free fall (detection), gyroscopic motion, ambient temperature, pressure (altitude), humidity, and light
• Allows for easy development of more advanced activity tracker functions (e.g., distance traveled, calories burned, sleep analysis, and more)
• Additional biometric measurement capability, such as heart rate, blood oxygen, and body temperature, can be added to this design using other Microchip reference designs
• BLE module is used to demonstrate smartphone/tablet IoT capability
• Low overall BOM cost due to high level of integration
• Powered from a single 3 V lithium coin cell battery
