BP Med 21 is an airbag blood pressure and ECG smartwatch. A side-insert airbag and a piezoelectric ceramic pump take oscillometric blood pressure readings on the wrist, while a Goodix GH3220T chip and nano conductive glass capture an ECG waveform. The 1.95-inch AMOLED display is a full-touch screen for everyday health check-ins.

Airbag Blood Pressure and ECG

BP Med 21 uses a piezoelectric ceramic air pump and a detachable, sealed side airbag in the strap. The watch checks measurement posture and filters readings taken in the wrong position. ECG capture uses a Goodix GH3220T chip and nano conductive glass. A one-tap mini health check records several metrics together. An AI heart-health report in the HealthWear app is for reference only.
