Researchers at the University of California, San Diego have developed a wearable ultrasound patch that continuously monitors blood pressure, offering a noninvasive alternative to traditional cuffs and invasive arterial devices. The patch, which adheres to the forearm, has shown promising results in tests with over 100 patients, closely matching readings from standard methods. This innovation could help manage hypertension by providing detailed trends in blood pressure fluctuations, and the team plans to refine the device and conduct large-scale clinical trials.

MIT researchers have developed a new method for deep brain stimulation using ultrasound instead of electrical impulses, delivered via a hair-thin fiber. This approach, tested in mice, can stimulate neurons to release dopamine, potentially offering a safer and more precise treatment for Parkinson's disease and other neurological disorders. The device, called ImPULS, avoids the corrosion and scar tissue issues associated with traditional electrodes and could also serve as a valuable research tool for studying the brain.
