A 3D-printed sensor with surface-wrinkled structures detects subclinical hypocalcemia in dairy cows by measuring the calcium-to-phosphate ratio in milk. With attomolar sensitivity and rapid ...

Traditional reflective SpO2 sensor algorithms often yield invalid measurements and poor accuracy in these areas. To address these challenges, this study proposes a novel photoplethysmography (PPG) ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level ...

You’ll learn about measuring blood oxygen saturation (SpO2), how to take and view readings, and which Apple Watch models still support the app. However, those who purchased the two latest Apple ...

Abstract: Objective: This paper describes the full development of a sensor for measuring optical heart rate (OHR) and blood oxygen saturation (SpO2). Methods: A wearable sensor with a new type of skin ...

Possessing the STALKER 2 Ward Sensors is one thing. Deciding who to give them to between Richter or Zotov is another altogether. It’s one of the game’s first major choices that forces you to ...
