Autonomous Ultrasonic System-on-Patch (USoP)
The Autonomous Ultrasonic System-on-Patch (USoP) is a landmark achievement in wearable ultrasound, representing the first fully integrated, wireless, and flexible system for continuous deep tissue monitoring. This device transcends the traditional "transducer + cable" paradigm by incorporating miniaturized control electronics, a data acquisition module, an internal battery, and Wi-Fi communications directly onto a flexible, skin-adherent patch. Operating at frequencies from 2 to 6 MHz, the USoP enables hands-free, multi-modal imaging (A, B, and M-mode) of cardiac activity, carotid arteries, and jugular veins without any physical tether. Its onboard machine learning (VGG13 model) automates data processing for real-time spatial tracking, making it the ideal core sensing platform for next-generation autonomous diagnostic wearables and remote patient management systems.
