Continuous health-tracking wearables like rings, bands, and watches have to read a pulse through skin, day and night, without draining a battery that has to last a week between charges. Vishay's VEMD8080 photodiode delivers the high responsivity across red, green, and IR wavelengths that accurate PPG heart-rate sensing depends on, detecting the faint light signals returning from blood flow beneath the skin even in a ring-sized form factor.
Behind every heartbeat is The DNA of tech.®
