Innovative Ultrasound Patch: A Leap Towards Personalized Medicine
Written on
Chapter 1: The Evolution of Wearable Technology
Wearable technology is reshaping our understanding of personalized healthcare. Devices like smartwatches now serve as fundamental health monitors, tracking various metrics such as heart rate and pulse. However, the advent of stick-on personalized patches is taking this evolution to a whole new level. Over the past year, I've explored numerous innovations, from wireless biosymbiotic devices to 3D-printed vaccine patches and comprehensive wearable health monitors.
Imagine a smartphone that not only displays your heart rate but also provides real-time images of your heart as it beats. While this may sound futuristic, we're closer to this reality than we might think. Researchers have already made significant strides in this direction.
Most individuals are familiar with ultrasound imaging, which offers a safe, non-invasive method for obtaining live images of internal organs. Skilled technicians use sound waves to target specific areas of the body, generating high-resolution images that assist doctors in diagnosing conditions and recommending treatments. Unfortunately, current devices are often bulky and lack portability.
Section 1.1: A Vision for Wearable Imaging
“We envision a few patches adhered to different locations on the body, and the patches would communicate with your cellphone, where AI algorithms would analyze the images on demand. We believe we’ve opened a new era of wearable imaging.”
— Xuanhe Zhao, Senior Author of the Study
Section 1.2: The MIT Innovation
To tackle the challenges associated with current ultrasound devices, engineers at the Massachusetts Institute of Technology (MIT) have developed a stamp-sized stick-on ultrasound patch capable of providing continuous imaging of internal organs for up to 48 hours. This innovative design connects the patches to instruments that convert reflected sound waves into images. Remarkably, the patch could have immediate applications, eliminating the need for technicians to hold the probe during monitoring.
Previously, researchers have tested stretchable ultrasound probes for portable, low-profile imaging, but these devices produced low-resolution images unsuitable for clinical analysis. MIT’s team has overcome this obstacle by combining a stretchy adhesive layer with a rigid transducer array, achieving high-resolution images over extended periods.

Chapter 2: The Hydrogel Advantage
Compared to traditional ultrasound gels, MIT’s hydrogel is elastic and flexible. This water-based material effectively transmits sound waves and is encased between two thin elastomer layers—one adhering to a rigid transducer array and the other sticking to the skin. Testing involved applying these patches to volunteers, generating high-resolution images of critical blood vessels and deeper organs like the heart, lungs, and stomach.
During trials, the patches maintained strong adhesion while capturing images during various activities such as sitting, standing, jogging, and biking. The 2 square centimeter, 3 millimeter thick patches underwent extensive testing on different body areas, allowing researchers to observe changes in various organs during diverse activities.

Looking ahead, the team aims to develop wireless functionality for these ultrasound patches, transforming them into wearable imaging products. Imagine the convenience if patients could bring these devices home from a doctor's office or purchase them over the counter at a pharmacy. The findings of this groundbreaking research were published in the Journal of Science.
