Blueberry-size capsule tracks core temperature from inside the body

Article excerpt

Researchers have developed a blueberry-sized capsule that measures core body temperature from inside the body, potentially offering more accurate readings than traditional oral or forehead thermometers. Unlike surface measurements, which can miss dangerous fevers or fail to detect genuine illness, internal tracking could help clinicians and patients distinguish between actual fever and ambient temperature effects. The innovation addresses a persistent challenge in medical care: knowing when someone is truly sick versus simply warm. While the technology's exact mechanism and timeline for clinical deployment remain unclear from available details, the device represents a step toward more reliable home and hospital monitoring.
