Now, Maxim Integrated Products, Inc. (NASDAQ: MXIM) has introduced a solid-state blood-pressure monitoring solution to more conveniently track this critical health indicator. Design engineers can develop blood-pressure trending solutions with the<strong> MAXREFDES220# <\/strong>reference design from Maxim. Comprised of a complete integrated optical sensor module, a microcontroller sensor hub and a sensing algorithm, the MAXREFDES220# optical blood-pressure trending solution can be embedded into smartphones or wearables. It enables users to place their finger on a device for 30-45 seconds while resting to measure blood pressure anywhere and anytime. The reference design includes the <strong>MAX30101 <\/strong>or <strong>MAX30102<\/strong> high-sensitivity optical sensor, as well as the <strong>MAX32664D<\/strong> sensor hub IC with built-in algorithms.<\/p>\n<ul>\n<li>For information about how to order MAXREFDES220# reference design, visit http:\/\/bit.ly\/MAXREFDES220<\/li>\n<li>For information about Maxim\u2019s optical biometric sensor hub algorithms, including how to order MAX32664D, visit http:\/\/bit.ly\/Maxim_Optical_Sensor_Hub_Algorithms<\/li>\n<li>For information about how to order MAX30101, visit http:\/\/bit.ly\/MAX30101_Maxim<\/li>\n<li>For information about how to order MAX30102, visit http:\/\/bit.ly\/MAX30102_Maxim<\/li>\n<li>For a hi-res image, visit http:\/\/bit.ly\/MAXREFDES220_Image<\/li>\n<li>For a chart with accuracy data, visit http:\/\/bit.ly\/Accuracy_Data_Chart<\/li>\n<\/ul>\n<p>The MAX30101 (using two LEDs) and MAX30102 (using three LEDs) pulse-oximeter and heart-rate optical sensor modules combine photodetectors, LEDs and analog front-end (AFE) electronics with an integrated cover glass. This integrated optical design and lenses-on-top approach enables optimal signal-to-noise ratio (SNR) for a small, lower cost and power-efficient module.
