The design features compact components suitable for creating efficient heart rate monitors with advanced functionality and performance.
Wearable devices are valued for compactness, often designed to be as small as conventional watches, wristbands, or finger scanners. As technology progresses, the challenge for designers is to integrate an increasing number of functions into these devices, with the size of each component playing a critical role in how many features can be included. Additionally, these devices are optimized for low-power usage, utilizing batteries as their primary power source. Given the limited size and energy capacity of the batteries, this is crucial to extend the device’s operational life. Most wearable devices operate in standby mode over 90% of the time, making low standby power consumption vital. Furthermore, as market demands shift towards higher precision, the accuracy of these devices has become a critical selling point, with only the most precise devices gaining acceptance in the market. The MAXREFDES1207 from Analog Devices (ADI) is a reference design tailored for wearable applications.
