ActivHearts™

Accurate Wearables & Hearables To Mobile Health

WBD101 is the only Asian startup that has extremely accurate heart rate measurement technology (ActivHearts™) using Photoplethysmography (PPG) that can be applied to smart hearables and wearables.

Our R&D focus on ensuring that accurate bio-signals can be obtained dynamically under motion and in a continuous real-time manner by using our patented OpticalFusion™ approach that removes motion artifact. OpticalFusion™ which involves the use of multiple photodiodes/sensors.

By removing the motion noise via our OpticalFusion™ approach instead of using accelerometer to calculate the displacement between the sensor and the skin (as our competitor do), we can preserve very detailed information that can be used to compute other bio-signals.

Access to Accurate Bio-signals for All

Our technology has accumulated over 1000 miles worth of purely accuracy testing, comprising of data from different ear shapes, gender and skin colours. This aggregate data can improve consumers’ physical well-being through a wide range of aeriobic exercises.

ActivHearts™ - Probably the World’s Smallest Heart Rate Sensing Tech for Smart Hearables

One of the challenges of PPG technology is that the PPG sensors pick up a lot of noise when the user is exercising, as it is very sensitive to motion. WBD101 technology uses multiple source and sensor pairs (OpticalFusion™) and advance digital signal processing (ActivHearts™)  to remove these motion noise.  
 
The latest generation of SmartBody™ processors makes use of Bluetooth Smart technology (BLE) that means you can easily have your physiological information displayed on your smartphone apps.

what can you deduce from heart rate?

  •  Calories and energy expenditure ​

  • Maximum Oxygen Uptake (VO2max) ​

  • Basal metabolic rate (BMR) ​

  • Metabolic Equivalent of Task (METs) ​

  • Heart Rate recovery time 

  • Fatigue / Stress / Emotion

  • Respiratory Rate 

  • Assessment protocols 

  • Training zones for Fat Burn, Muscle Build and to avoid over-exertion of the heart 

  • Heart Rate Variability (HRV) 

  • R-R Interval (RRI)
