A pulse oximeter is a device that clips on your finger, toe, or earlobe to measure blood oxygen saturation. Here's how it works and how to read it.
Rohde & Schwarz has expanded its high-end R&S ZVA network analyzer with the addition of the R&S ZVA-K7 software option for pulse profile measurements on semiconductors and antenna systems. The ...
We’re always looking for interesting biohacks here on Hackaday, and this new research article describing a calibrated pulse oximeter for different skin tones really caught our attention. Their idea ...
Researchers identify measure of pulse rate that can predict faster cognitive decline in older adults
Healthy hearts are adaptable, and heartbeats exhibit complex variation as they adjust to tiny changes in the body and environment. Researchers have applied a new way to measure the complexity of pulse ...
While ac internal resistance (ACIR) measurements are quite common and somewhat standardized when measuring lithium-ion cells, dc internal resistance (DCIR) measurements are nonstandard and generally ...
Generating ultrashort laser pulses that last a few femtoseconds is a highly active area of research that is finding applications ranging from micromachining to eye surgery. For optimum results it is ...
