Wearable technologies are advancing rapidly and can provide a multitude of skin-based physical and chemical readouts. However, harnessing wearable technologies for internal imaging applications such as ultrasound – which provides crucial information on organ function and disease – has been challenging.
Now scientists have engineered a stick-on wearable ultrasound device for continuous monitoring.
Bioadhesive ultrasound for long-term continuous imaging of diverse organs.
Wang Chonghe et al. Science (New York, N.Y.) 2022 7 (6605) 517-523
Ultrasound is widely used for the noninvasive imaging of tissues and organs, but this method requires close contact between the transducer and the target area. This can make it difficult to acquire images over a long period of time, especially if the patient needs to be mobile. A new study describes a wearable ultrasound imaging device. A rigid piezoelectric probe array is bonded to the skin with an acoustically transparent hydrogel elastomer. In vivo testing showed that the device could be comfortably worn for 48 hours, and hooking the array up to a commercially available ultrasound platform allowed for continuous ultrasound images of the carotid artery, lung, and abdomen.
Precision Health Innovations in the Pandemic Era
D Rasooly et al, CDC Blog Post, July 8, 2022
Two recent articles, one in Nature Medicine and another in Nature Biotechnology, highlight areas of health innovation that have been accelerated by the COVID-19 pandemic. This blog post focuses on two precision health applications of technology—(1) genomics and (2) wearable devices and smartphone apps—that are likely to have a lasting impact beyond the pandemic. Increased interest in these applications is reflected in the scientific literature captured by the COVID-19 GPH database
Shaping the future of cardiovascular medicine in the new era of wearable devices.
Gehr Sinje et al. Nature reviews. Cardiology 2022 6
Wearable devices are widely used and have a high level of societal acceptance, opening unimagined and unexploited possibilities in cardiovascular medicine. In this Clinical Outlook, we highlight the disruptive potential of wearables for cardiovascular disease prevention, diagnosis and management, and suggest strategies for quickly and safely translating these lifestyle products into medical devices.
