Who knows my heart? Opportunity and extension testing of ECG/PPG wearable devices

Allion Labs/ Otto Wei

Chronic cardiovascular diseases can be detected by using hospital electrocardiogram (ECG/EKG) measuring instrument. However, some typical symptoms of acute heart disease, such as premature ventricular contractions PVCs, are hard to be detected early. PVCs is generally accompanied with hypertension, and frequent PVCs could cause sudden death. 

But now, patients can use a wearable device to detect heart signals and receive warnings in advance. Although ECG’s pathological features are more precise when using electric signals, using optical ways such as photoplethysmography (PPG) to measure cardiac rate is relatively simple.

What will the next-generational laptops be like?

The next generation of laptop not only has a thinner appearance, but also faster  system performance. In the new generation product design, supporting Artificial Intelligence (AI) is an indispensable feature that helps computer to understanding user’s behavior.

Battery life is a key factor for consumers to purchase laptops. However, conventionally in the pursuit of long-lasting battery life, the laptop will inevitably be bigger and heavier. The new generation of laptop can overcome this problem via optimized power management, coupled with fast charging technology such as Power Delivery (PD). These new features will greatly enhance the endurance of the laptop, providing users with nearly a full day of work time.
