Vitalgram® transforms the way we experience the world from data monitoring to prevention and watching that will afford a better safety, reliable and comfortable lifestyle for everyone.
                       Fig. 1 How Vitalgram® works

AffordSENS Corporation premises that Vitalgram® can be properly used for the purpose of health monitoring by general users (not by doctors).
Until the company complies prescribed condition and obtains the approval and license etc. from relevant authorities, the company stipulates that diagnostic action by using this product cannot be conducted; doctors are not able to use it for patients.

Major Features and Advantages

Strengths and selling points of Vitalgram® technology

  • Simple to use - wear it and leave it. Vitalgram® is one of the world most tiny, lightweight, flexible, bendable and wearable patch-type wireless multi-vital sensing technology which is designed for sensing in anytime, anywhere, without disturbing daily life.

  • Fusion of Multi-sensing:
    • Vital sensing: Electrocardiogram (ECG / EKG), heart rate, respiration rate, body skin and core-body temperature
    • Body posture, behaviour and step count: 3-axis accelerometer and gyroscope
    • Environmental sensing: Ambient temperature, humidity & atmospheric pressure (altitude).
  • Onboard real time data processing to compute critical vital data including heart rate, respiration rate and heart rate variability (HRV) for mental stress level indication as well as core body temperature and accumulation of heat road for thermal stress level indication.

  • Transmit all the collected data to mobile or cloud system in real time for healthcare monitoring and emergency prevention.

  • Wireless, low power consumption and rechargeable.

Technology Data

Possible applications

After wearing Vitalgram® on the chest, it will continue sensing the vital signals including electrocardiogram (ECG / EKG), heart rate, respiration rate, body skin and core-body temperature. Not only vital sensing, Vitalgram® is also capable to monitor the body’s motion and posture by 3-axis accelerometer and gyroscope. Moreover it is also monitoring ambient temperature, humidity and atmospheric pressure at the same time. Furthermore, by using the onboard data processing, Vitalgram® computes critical vital data including heart rate, respiration rate and heart rate variability (HRV) for analyzing the activation of the sympathetic and parasympathetic nervous system to indicate the stress level in real time. All the data is transmitted to mobile or cloud system for healthcare monitoring and emergency prevention.

By combining the collected multi-vital data, location-based service (LBS) data and applying AI analyses, it is capable to establish the advanced health monitoring system for following applications:

  • Home / Nursing / Elderly healthcare / Remote health monitoring
  • Rehabilitation & Preventive-rehabilitation / Accelerate patient recovery
  • Sports / Fitness / Physical training
  • Workers health monitoring (e.g. stress, heat stroke)
  • Emergency prevention for high risk occupations: Police / Firefighter / Army
