Current developments in wearable ultrasound technologies have paved the way for hands-free data collection. However, certain barriers, like the probes needing wireless connections and loss of track for moving targets, still exist. To overcome such barriers, researchers have developed a fully integrated autonomous wearable device called ultrasonic-system-on-patch (USoP; Cover image) to monitor deep tissues even in moving subjects. The device has a flexible control circuit, ultrasonic probe, and transducers for wireless communication.
USoP was found to c ontinuously track physiological signals from tissues at a depth of up to 164 mm . It could monitor physiological signals like central blood pressure, heart rate, and cardiac output for 12 hours in mobile subjects. A smartphone application is designed to display and analyze the data from USoP. Additionally, machine learning is also used to…
