Earbuds can be used to monitor brain health
An international research team has uncovered the next frontier in monitoring brain health, and the key is in technology that millions of people are already using every day—earbuds. The world-first study found that commercially available earbuds have the capability to detect and classify brain activity, simply by measuring subtle changes in users' hearing. The team used acoustic sensors in earphones to assess cognitive load—the mental effort that shapes learning, task performance and early c…

Today I will be mostly diving down the #3dprinting rabbit hole. First task is a couple of mounts for the hall effect #sensors for my garage door opener.

Scientists camouflage heart rate from invasive radar-based surveillance
It's a typical workday and you sign onto your computer. Unbeknownst to you, a high-frequency sensing system embedded in your work device is now tracking your heart rate, allowing your employer to monitor your breaks, engagement, and stress levels and infer alertness. It sounds like a dystopian scenario, but some believe it's not so far from current reality.

Superconducting detector captures hot spots with submicron resolution
A research team from Osaka Metropolitan University proposed using a current-biased kinetic inductance detector with submicron 400 megapixels to image hot spots induced by a localized external stimulus over a 15 × 15 mm2 area. The team utilized a delay-line technique to trace the propagation of internal signals for a pair of signals arising from each hot spot.

Ultrasonic sensor capable enables cuffless, non-invasive blood pressure measurement
A new technology has been developed that enables cuffless noninvasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter—without the need for a traditional cuff. The technology is expected to serve as a core component in future wearable health care devices and smart medical monitoring platforms.
