WATCH-LIKE SENSOR MONITORS PULSE WITHOUT BATTERIES
In a paper in the journal Nano Energy, researchers describe their invention, built via 3D printing of nanomaterials on flexible substrates for real-time and wireless monitoring of vital signs. The current prototype serves as a self-powered radial artery pulse monitor, but other aspects of health—such as heart rate, body temperature, or blood pressure—can be gauged by simply changing...

Pulse pressure: A game changer in the fight against dementia
Promoting blood brain barrier health by reducing elevated pulse pressure in blood could be a promising new preventative solution and/or treatment for dementia. A recent paper published in Frontiers in Neuroscience, outlines a pulse-pressure-induced pathway of cognitive decline that sheds light on why previous treatments for dementia may have failed and proposes promising new directions...

Masimo’s High Accuracy RD SET Pulse Oximeters Cleared by FDA
Masimo won FDA clearance for its RD SET sensors that feature the company’s “Measure-through Motion” and “Low Perfusion SET” pulse oximetry. The new disposable oximeters are supposedly twice as accurate than Masimo’s previous offerings for patients over 3 kg, having an accuracy spec of 1.5% at 1 standard deviation, compared to 3% before. The devices...
