At present, wearable health monitoring products are in full swing, providing an unprecedented way for people to obtain health data, helping professionals and end-users to achieve active health management and early prevention. prevent the occurrence of chronic diseases.Through continuous innovation, developers help users understand their own health status more deeply, and open the door to improve human health. 



Today, Maxim Integrated Products, Inc (NASDAQ: MXIM) announced the launch of MAXM86146's built-in dual photodetector optical sensor solution, the industry's thinnest solution that helps designers quickly and easily design wearable health and fitness products. The module includes advanced algorithms for heart rate and oxygen saturation (SpO2) monitoring, and supports activity classification to provide users with a true turnkey solution. The device is small in size and easy to design, which can realize the innovative design of biological detection with less space, and accelerate the development process of high-precision and continuous monitoring equipment. 







Compared with discrete solutions, MAXM86146 helps designers reduce the thickness of advanced wearable products by 45 per cent. In addition, the module provides a ready physical sign detection algorithm that can measure vital signs according to the strictest medical standards, thus 
The MAXM86146 evaluation system (EV system) allows for the quick evaluation of the MAXM86146 optical module for applications at various sites on the body, particularly the wrist. MAXM86146 supports UART, I2C, and SPI compatible interfaces. MAXM86146 has two optical readout channels that operate simultaneously. The EV system allows flexible configurations to optimize measurement signal quality at minimal power consumption. It helps the user quickly learn about how to configure and use the MAXM86146. The EV system consists of two boards. MAXSensor BLE# is the main data acquisition board while MAXM86146_ OSB# is the sensor daughter board for MAXM86146. The EV system can be powered using the USB-C supply or LiPo Battery. The EV system comes with a MAXM86146CFU+.
