Wearable ultrasound: Design, development, and application in precision medicine

Wearable ultrasound technology has recently emerged as a promising tool in medicine that combines advances in materials science, electronic engineering, and medical imaging to provide innovative solutions for clinical diagnosis and therapy. By miniaturizing ultrasound devices and incorporating flexibility and intelligence, this technology has enabled close skin contact and continuous real-time monitoring of physiological parameters. Compared with conventional ultrasound systems, wearable devices not only enhance patient comfort but also overcome the limitations of traditional ultrasound devices, paving the way for multisystem and multiscenario medical applications. Furthermore, wearable ultrasound devices offer unique advantages in specialized settings, such as intensive care monitoring, drug delivery surveillance, and rehabilitation outcome assessment, establishing them as a key enabler of precision medicine. However, despite their significant potential, wearable ultrasound devices face challenges related to technological maturity, data processing capabilities, and clinical standardization, which require further investigation and refinement.
