Product Details

The MAX-HEALTH-BAND wrist-worn heart-rate and activity monitor provides a simplified means to extract high-accuracy vital signs and raw data from health sensors for wearable designs. This unique evaluation and development platform uses the MAX86140 optimized optical pulse-oximeter/heart-rate sensor and the MAX20303 wearable power management solution, and showcases Maxim’s motion-compensated health sensor algorithms. The MAX-HEALTH-BAND streams algorithm output and raw data from the health sensors via Bluetooth^® onto a smartphone app for customized algorithm development. The platform is also available for white-box license.

In addition to raw PPG and accelerometer data, the MAX-HEALTH-BAND monitors steps, activity classification, heart rate, and interbeat intervals for heart-rate variability. The MAX-HEALTH-BAND comes with a wrist-worn heart-rate and activity band, a USB charging cable, and instructions for downloading the Android-based application.

Product Details

The MAX86140/MAX86141 Evaluation System (EVSYS) allows for the quick evaluation of the MAX86140 and MAX86141 optical AFE for applications at various sites on the body, particularly the wrist. Both MAX86140 and MAX86141 supports standard SPI compatible interface. MAX86140 consists of a single optical readout channels, while MAX86141 has two optical readout channels that operate simultaneously. The EVSYS allows flexible configurations to optimize measurement signal quality at minimal power consumption. The EVSYS helps the user quickly learn about how to configure and use the MAX86140 and MAX86141.

The EVSYS consists of three boards. MAXSensor BLEEK# is the main data acquisition board while MAX86140OSBEK# and MAX86141OSBEK# are the sensor daughter boards for MAX86140 and MAX86141 respectively. The EVSYS can be powered using the USB-C supply or LiPo Battery.

The EVSYS comes with a MAX86140ENP+/MAX86141-ENP+ in a 24-bump wafer-level package (WLP).
