Pixel Watch 3: Security on Your Wrist
FDA Approves Technology That Detects Absence of Vital Signs, Automatically Triggers Emergency Response in Critical Situations
Isabella V2 March 2025

 


 The recent FDA clearance allows the Pixel Watch 3 to autonomously activate emergency services in the absence of vital signs, thanks to advanced sensors and intelligent algorithms, improving the safety of users in the United States and other international markets.

Key points:

  • FDA approves the loss-of-pulse detection feature.
  • The Pixel Watch 3 can automatically call emergency services.
  • It uses multiple sensors and algorithms to ensure accuracy.
  • The feature is implemented in 15 countries, with further expansion planned.


The Food and Drug Administration has granted regulatory approval for the Loss of Pulse Detection technology built into the Pixel Watch 3, a device that, through a combination of heart rate sensors, infrared technologies, red lights and motion detection, makes an automatic call to emergency numbers the moment no pulse or signs of activity are detected, while simultaneously transmitting geographic location; the system, which was developed through intensive research and clinical trials-which involved the collaboration of experts in the field, including cardiologists and specialized practitioners, and the use of simulated scenarios performed with stuntmen to optimize the AI algorithm-is part of a framework of innovations aimed at providing timely support in critical situations, following the model of other technologies found in wearable devices marketed in markets such as the United Kingdom, France, and Switzerland, and now extending to the U.S. territory, with the goal of reducing false alarms through the ability to recognize the moment the user removes the watch; the feature, scheduled to be activated by the end of March, is part of the broader landscape of advanced health applications, in which the synergy between technological innovation and regulation is a key preventive tool in the medical field.
 The integration of advanced technologies into wearable devices highlights how precision and regulation can work together to provide immediate solutions in emergency situations.
