In the recent past I have seen a lot of questions from fellow community members about how to calculate Oxygen Saturation- SpO2 using "Photoplethysmography" or PPG. The World is going through a tough time and  lot of people are infact talking about the scope of home monitoring and remote monitoring. In this blog post I would like to explain how SpO2 is calculated using a cheap PPG sensor.   The setup : BeagleBoneBlack Rev 3 (https://beagleboard.org/black) MAX30100 (https://www.maxi ...
I grew up in the 90s and early 2000’s watching TV shows like The Magic School Bus, and Osmosis Jones, and as a result, I would often daydream and fantasize about being able to shrink down to microscopic size and explore the inner workings of the human body. I would doodle and sketch little spaceship-like vehicles that could use robotic arms to grasps medicines and deliver them directly to cancer cells and envisioned swarms of robots that deployed like fighter jets to destroy bad bacteria a ...
It’s something that until recently has only been possible in movies and science fiction, but now biomedical engineering researchers at the University of Utah may have finally cracked the code on mind-controlled prosthetics that allow their user to regain sense of touch and feel. Named after Luke Skywalker’s robotic hand from Star Wars: The Empire Strikes Back, the “LUKE Hand” is a new type of robotic prosthetic hand was first developed some 15 years ago by DEKA Research & ...
A batch of beer that brews itself? Water that adjusts its own pH? A completely organic carbon monoxide detector? With bacterial DNA circuitry, such things are now possible.  Bacteria can be programmed to respond to changes in temperature, pH, oxygen level. (via MIT)   After Kosuri et al at Harvard figured out a way to store data within naked DNA in 2012, researchers at MIT have built on that engineering to incorporate such information into biological circuits, programs embedded within ...
Monitoring blood pressure has evolved from expensive, large equipment used only by professionals to something that we can all easily use. Huge advancements thanks to MEMS sensors and microcontrollers now allow for precise readings from much smaller form factors such as a watch, activity monitor or other wearable. Progression of MEMS sensors in the medical field will have increasing sophistication of algorithms that can detect accurate signals from the equipment. More information on h ...

ECG signal amplication

Posted by kasba May 10, 2014
Good morning. I just received my Raspberry Pi. I am a very very beginner, with some knowledge in programming, trying to learn JAVA but a dummy in electronics. Could someone tell me how to amplify an ECG signal so that it can be "seen" by the GPIO? Between 1 and 5 mV. Thank you very much. ...

Fujitsu, one of Japan’s well-known information and communications technology leaders, has just announced the development of a smartphone and tablet app that will help people monitor their health over time without the need of operating specialized equipment or sitting still for long periods of time. The real-time heart pulse monitors helps users to keep track of their heart rate activity by use of a face imaging technology that utilizes a computer's camera to measure brightness variations i ...
(Left) 3D printing nozzle for living tissue concept (Right) real-world printed tissue samples (via University of Oxford & Science/AAAS)   We have seen 3D printers create many things from dresses and art, to gun models and cars. Now researchers at Oxford University have created a 3D printer that is capable of printing materials with properties of human tissues. Gabriel Villar, the creator of the printer, is a PhD student supervised by Professor Hagan Bayley. His printer creates extremel ...
