We’ve always been interested in fluidic computers, a technique that uses moving fluids to perform logic operations. Now, Spectrum reports that researchers have developed an electronics-free contact lens that monitors glaucoma and can even help treat it. The lens is made entirely of polymer and features a microfluidic sensor that can monitor eye pressure in […]
Imagine you and your friend are enjoying a nice sunny day, and BAM — they start to have a severe allergic reaction to who knows what. You have an EpiPen, but your friend is on the other side of a field! The solution? Obviously [Emily The Engineer] has only one option: build an entire EpiPen […]
Odds are, you’ve taken pills before; it’s a statistical certainty that some of you reading this took several this morning. Whenever you do, you’re at the mercy of the manufacturer: you’re trusting that they’ve put in the specific active ingredients in the dosage listed on the package. Alas, given the world we live in, that […]
Alzheimer’s disease remains a frustratingly difficult condition to manage for the millions of patients affected worldwide and their families. The cause of the disease is still not properly understood, and by the time memory loss and cognitive decline become apparent, the underlying brain pathology has often been quietly building for decades. Soon, though it may […]
With more and more sensors being crammed into the consumer devices that many of us wear every day, the question of where medical devices begin and end, and how they should be regulated become ever more pertinent. When a ‘watch’ no longer just shows the time, but can keep track of a dozen vital measurements, […]
Let’s face it; remembering a bunch of passwords is the pits, and it’s just getting worse as time goes on. These days, you really ought to have a securely-generated key-smash password for everything. And at that point you need a password manager, but you still have to remember the password for that. Well, Motorola is […]
The human body is remarkably good at handling repairs. Cut the skin, and the blood will clot over the wound and the healing process begins. Break a bone, and the body will knit it back together as long as you keep it still enough. But teeth? Our adult teeth get damaged all the time, and […]
Sleep apnea is a debilitating disease that many sufferers don’t even realize they have. Those afflicted with the condition will regularly stop breathing during sleep as the muscles in their throat relax, sometimes hundreds of times a night. Breathing eventually resumes when the individual’s oxygen supply gets critically low, and the body semi-wakes to restore […]
For those born with certain types of congenital deafness, the cochlear implant has been a positive and enabling technology. It uses electronics to step in as a replacement for the biological ear that doesn’t quite function properly, and provides a useful, if imperfect, sense of hearing to its users. New research has promised another potential […]
While EEG research might help you figure out extrasensory perception, we won’t be betting on it. However, if you want to read EEG data and use an ESP32, [Cerelog-ESP-EEG] might be the right project for you. The commercial project is an 8-channel biosensing board suitable for EEG, EMG, ECG, and brain-computer interface studies. However, the […]
