Smart wristbands may spot malaria before symptoms strike

This early-stage study tests whether wearable biosensors (like a wristband or earphones) can detect malaria infection before symptoms appear. 32 healthy adults will be exposed to the malaria parasite or a placebo in a controlled setting. Researchers will compare biosensor readings (temperature, heart rate, breathing, sleep, skin/muscle activity, voice) with standard blood tests to see if the devices can catch infection early.
