MLX90632 - Medical Grade FIR (Far Infrared) Sensor

Melexis released the smallest medical grade FIR (Far Infrared) sensor, assembled in a surface mount 3x3x1mm QFN package for use in a variety of applications, including wearables and, in particular, advanced in-ear-devices (so-called hearables) and clinical point-of-care applications where highly accurate human body temperature measurement is required. The MLX90632 is based upon Melexis' established far infrared (FIR) technology that utilizes the fact that all objects emit heat radiation. Miniaturized far-infrared sensors are typically sensitive to thermal disturbances, however, the MLX90632 mitigates this effect through sophisticated compensation algorithms; delivering high levels of thermal stability.

 

The new medical-grade MLX90632 sensor is optimized for the normal human body temperature range, where it features medical-grade accuracy of ± 0.2 °C by leveraging advanced in-factory calibration procedures. The sensor includes the sensor element, signal processing, digital interface and optics in a single 3x3x1mm QFN Package allowing it to rapid and simple integration into a wide variety of space constrained modern applications.

 

The device is an ideal solution for the applications in ultra-small modern health monitoring devices, such as portable diagnosis tools capable of monitoring body temperature continuously with its features such as small size, high thermal stability and optimization for human body temperature. The new sensor is also suited for more classic medical devices such as forehead or ear body thermometers. The sensor can operate in the temperature range of -20 °C to 85 °C and Factory calibrated with I2C digital interface, 50° field of view.

The MLX90632 sensor is available at Melexis and can be read more at Melexis Website.
