Do you ever wonder what is in the air you breathe? Or maybe you have hay fever and want to know what kind of pollen makes you sneeze in spring? Questions like that prompted me to build a simple device for capturing airborne particles so they can later be examined under a microscope. Before you …

When I first built the Heart rate measurement through fingertip project, the infrared LED and photodiode used for finger photoplethysmography were actually from salvaged parts, and therefore, I could not provide specifications for them in the article. As a result of that it takes quite a bit of time to replicate that project with a different set …

For our final project we implemented a speech recognition eye test that is capable of performing the entire Snellen eye test on its own. It starts by displaying large letters and waits on the user to guess which letter has been displayed. The user speaks his/her guess into the microphone. The speech recognition portion uses …
Step 1: Sensor assembly The sensor unit consists of an infrared light-emitting-diode (IR LED) and a photo diode, placed side by side, and the fingertip is placed over the sensor assembly, as shown below. The IR LED transmits an infrared light into the fingertip, a part of which is reflected back from the blood inside …

Introduction Heart rate measurement indicates the soundness of the human cardiovascular system. This project demonstrates a technique to measure the heart rate by sensing the change in blood volume in a finger artery while the heart is pumping the blood. It consists of an infrared LED that transmits an IR signal through the fingertip of …

Fast Facts: NYU Abu Dhabi researchers have developed a microchip that can isolate T cells, in a systematic and precise manner. T cells are a type of white blood cell that is important to the immune system and is at the core of immunity, the system that tailors the body’s immune response to specific pathogens …
Inspired by the smart technology of a hand-held game controller, Dr. Joshua Broder of Duke University walked away the ultimate winner in the inaugural Point-of-Care Ultrasound (POCUS) Research Challenge offered by the Emergency Medicine Foundation (EMF) and GE Healthcare (GE). In a first-of-its-kind research partnership, EMF and GE launched the POCUS research challenge designed to push the boundaries of ultrasound …

Heart Beat rate is most important parameter in monitoring any person’s health. In the modern era of wearable devices, there are lot of devices which can measure heartbeat, blood pressure, footsteps, calories burnt and lot of other things. These devices has pulse sensor inside them to sense the pulse rate. Today, we will also use …
