MediCare-X is a wearable system with pulse oximetry, heart-rate and fall detection sensors plus an alert button linked to a Wi-Fi module. It monitors oxygen (below 95%) and heart rate (below 60 BPM) 24/7, automatically sending emergency notifications to family members via an app. Elderlies can also press the button when in distress. Unlike typical smartwatches, MediCare-X combines health monitoring with an instant alert system for faster help.
