Maxim Integrated Products, Inc. announces a news, which the introduction of the MAX86150-the latest biosensor module， consisting of LEDs, photodetectors and ECG analog front ends (AFEs), the industry's first high-precision, FDA-approved PPG and ECG products for compact, energy-efficient designs. Widely used in mobile phones, laptops, tablets and smart speakers.
It has always been a challenge to achieve both PPG and ECG simultaneous measurements, because designers must use two separate biosensors, both of which take up more board space and power than mobile devices can afford. In addition, achieving high-precision measurements can be challenging, especially when blood flow is slow or the skin is dry, the sensitivity of the sensor may be affected. The MAX86150 successfully overcomes these challenges by simultaneously acquiring PPG and ECG and providing the highest sensitivity pulse transit time. To reduce battery drain, the module supports software shutdown with standby current approaching zero and allowing the supply voltage to remain active. The MAX86150 optical module is available in a 3.3mm x 6.6mm x 1.3mm, 22-pin package.
High precision: As an important indicator of noise suppression capability, the module's common mode rejection ratio is 136dB, which is higher than similar products in the current market. Its 100mA, high dynamic range LED driver enables higher sensitivity in a variety of skin types. In addition, the ECG sensor has a very low contact impedance, enabling even higher precision measurements for dry skin.
Long battery life: 0.7μA (typ) ultra-low shutdown current to minimize battery drain. Power consumption is lower than the nearest competing device, further extending battery life.
Easy to deploy: The module uses dry electrode operation to obtain high-precision readings without the need for gel, liquid, viscous or wet electrode pads in other parts of the body.
Small size: The ECG sensor and optical PPG sensor are integrated in the same size as the stand-alone ECG sensor, saving space and providing more functionality.
