AI Wearables that Keep First Responders Working Safely

SLT Lab’s AI wearables and software analyze biometric data to protect the long term health of firefighters, law enforcement officers, paramedics, and other first responders.

The SLT Wellness App

The SLT Wellness Index

We calculate overall wellness for first responders to help them understand their physical and mental health, identify risk factors, and take the right precautions.


Our wearables measure biometric and environmental data to assess real-time risk. First responders can self-report how they are feeling, both physically and mentally. Our algorithm is the result of more than 10 years of research. It combines data from our wearables with existing information about each first responder.

The result is an easy-to-understand Wellness Index Score, along with specific recommendations for first responders and their managers.


The First Responder Safety Ecosystem


Building a Safer Future for First Responders

Our technology is built on more than a decade of academic research at the Survivability Signal Intelligence Research Center at Hanyang University in Seoul, which has been designated as a Convergence Research Center by the National Research Foundation of Korea.


Launch a functional prototype built around the widely available Apple Watch


Conduct extensive testing with rescue services around the world


Develop a custom wearable that meets the specific needs of first responders

Help Create a Healthier Future for First Responders

We have proven our concept in  South Korea with support from the National Research Foundation. Now we are seeking opportunities for global cooperation.

  • Pilot Projects with public agencies
  • Proof of concept with emergency response services
  • Partners for commercialization
