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 earphones and the skin (wrist watches, forehead, chest and arm).

Our R&D focus on ensuring that accurate physiological signals can be obtained dynamically under motion and in a continuous real-time manner by using our patented OpticalFusion™ approach that removes motion artifact.

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 physiological information.

Access to Accurate Biodata for All

What’s even better is that our technology, has been tested for more than 1000 accumulated miles with different ear shapes, gender and skin colours, enabling useful data to be gathered that can improve consumers’ physical well-being through a wide range of exercises.

ActivHearts™ - Probably the World’s Smallest Heart Rate Measurement Earbud Design

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 

  • 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)
