The nervous system does an astonishing job of tracking sensory information, and does so using signals that would drive many computer scientists insane: a noisy stream of activity spikes that may be ...

• The skin mainly relies on the TRPM8 sensor, whereas internal organs primarily depend on the TRPA1 sensor, explaining differences in the perception of external and internal cold. A research team led ...

Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging from hospital-grade pulse oximeters to consumer wearables that track heart ...

As wearable health monitoring advances, the demand for flexible pressure sensors that combine high sensitivity, full-range linearity, and medical-grade accuracy continues to grow. Now, researchers ...

Ramadan fasting is sacred for many, but going without food and water from sunup to sundown can harm health; researchers now monitor hydration in real time via a simple skin-touch signal. White House ...

Scientists have developed a fully transparent skin sensor that accurately measures UV radiation, detecting light and converting it to electrical signals. So when the Sun's rays reach damaging levels, ...
