Check out this wearable ultrasound patch from the lab of Sheng Xu, transforming clinical applications for patient recovery and care.

#mdpiSTD Weclome to read the paper "Objective Gait Analysis Using a Single-Point Wearable Sensor to Assess #Lumbar Spine Patients Pre- and Postoperatively" from the team of Ralph Mobbs and WAGAR. The study explores the use of a single-point wearable sensor for objective gait analysis in lumbar spine patients before and after surgery. It investigates how changes in gait metrics, measured by this sensor, correspond to patients' recovery and compares these results with healthy controls. The study's findings highlight significant improvements in gait asymmetry and variability post-surgery, which correlate well with improvements in the Oswestry Disability Index (ODI), a standard measure of disability. The research underscores the potential of using such wearable sensors in routine clinical assessments to provide objective data on patient recovery post lumbar #spine #surgery. https://lnkd.in/gW3Gkkmy

Ultrasound has gone ultrasmall (thanks in part to #ai among other amazing innovations). I wonder what wearables or other (music-making?) doohickies could evolve from this breakthrough? #deepthoughts "In the next five years, expect to see miniature passive medical implants with ultrasound MEMS chips, in which power and data are remotely transferred using ultrasound waves. Eventually, these handheld ultrasound probes or wearable arrays could be used not only to image the anatomy but also to read out vital signs like internal pressure changes due to tumor growth or deep-tissue oxygenation after surgery. And ultrasound fingerprint-like sensors could one day be used to measure blood flow and heart rate."

HOW ULTRASOUND BECAME ULTRA SMALL This is only the beginning for miniaturized ultrasound. Several of the world’s largest semiconductor foundries, including TSMC and ST Microelectronics, now do MEMS ultrasound chip production on 300 and 200 mm wafers, respectively. In fact, ST Microelectronics recently formed a dedicated “Lab-in-Fab” in Singapore for thin-film piezoelectric MEMS, to accelerate the transition from proofs of concept to volume production. Philips Engineering Solutions offers CMUT fabrication for CMUT-on-CMOS integration, and Vermon in Tours, France, offers commercial CMUT design and fabrication. That means startups and academic groups now have access to the base technologies that will make a new level of innovation possible at a much lower cost than 10 years ago. With all this activity, industry analysts expect ultrasound MEMS chips to be integrated into many different medical devices for imaging and sensing. For instance, Butterfly Network, in collaboration with Forest Neurotech, is developing MEMS ultrasound for brain-computer interfacing and neuromodulation. Other applications include long-term, low-power wearable devices, such as heart, lung, and brain monitors, and muscle-activity monitors used in rehabilitation. In the next five years, expect to see miniature passive medical implants with ultrasound MEMS chips, in which power and data are remotely transferred using ultrasound waves. Eventually, these handheld ultrasound probes or wearable arrays could be used not only to image the anatomy but also to read out vital signs like internal pressure changes due to tumor growth or deep-tissue oxygenation after surgery. And ultrasound fingerprint-like sensors could one day be used to measure blood flow and heart rate. One day, wearable or implantable versions may enable the generation of passive ultrasound images while we sleep, eat, and go about our lives.

💫 Imagine having a handheld ultrasound probe that fits in your lab coat pocket and yet provides high-quality images of deep organs and shallow veins with sweeping 3D views! Is this the future of medical imaging? A startling change is taking place in medical ultrasound technology. The bulky, cart-bound ultrasound machines with multiple probes dangling are being replaced by miniaturized, handheld probes that connect to smartphones, which offers flexibility and portability! The first miniaturized, handheld ultrasound probe was offered in the market in 2018, and since then, the technology has evolved rapidly. This revolutionary capability is made by silicon ultrasound technology, utilizing microelectromechanical systems (MEMS). These tiny systems pack an impressive number of transducers—devices that convert electrical signals into sound waves and vice versa—onto a mere 2-by-3-centimeter silicon chip. By fusing MEMS transducer technology with more sophisticated electronics on a single chip, these scanners not only match the quality of traditional imaging and 3D measurements but also unlock many new possibilities! Applications of Miniaturized Ultrasound Technology: - Medical Imaging: Handheld ultrasound probes provide high-quality images of various body parts, including deep organs and shallow veins, with a single probe, enabling comprehensive diagnostics. - Point-of-Care Diagnostics: With advancements in artificial intelligence (AI), these handheld probes may soon be operable by untrained professionals in any setting, expanding access to diagnostic capabilities beyond clinics. - Remote Monitoring: Miniaturized ultrasound technology allows for continuous monitoring of health metrics in real-time. This could enable remote monitoring of patients' health conditions, providing timely interventions when necessary. - Wearable Technology: MEMS ultrasound chips could be integrated into wearable devices for long-term monitoring of vital signs, such as heart rate, lung function, and brain activity. These devices could be used in rehabilitation and other healthcare applications. - Implantable Devices: In the future, passive medical implants with ultrasound MEMS chips could enable remote monitoring of internal pressure changes, tumour growth, and tissue oxygenation. As a result, this technology could enhance post-surgery care and provide valuable insights into patients' health status. As we continue the evolution of miniaturized ultrasound technology, the possibilities for improving patient care are endless!

MIT researchers have designed a wearable ultrasound monitor, in the form of a patch, that can image organs within the body without the need for an ultrasound operator or application of gel. In a new study, the researchers showed that their patch can accurately image the bladder and determine how full it is. This could help patients with bladder or kidney disorders more easily track whether these organs are functioning properly, the researchers say. This approach could also be adapted to monitor other organs within the body by changing the location of the ultrasound array and tuning the frequency of the signal. Such devices could potentially enable earlier detection of cancers that form ...

Med Tech in Focus:   Wearable Ultrasound Patch Offers Continuous Cerebral Blood Flow Monitoring Researchers at University of California San Diago have developed a postage-stamp sized ultrasound patch that can continuously monitor three-dimensional cerebral blood flow in real time. The technology is worn on the temple and is composed of silicon embedded with several layers of soft, stretchy electronics that produce and enhance ultrasound signals. Currently, a technician uses a Doppler ultrasound device on a patient’s head at specific times each day to monitor blood flow. That procedure has limits because such measurements can vary depending on the accuracy of the technician and data can fluctuate between readings.  The device is connected by cables to a computer and uses ultra-fast imaging and AI to collect and post-process data about the brain’s blood vessels. Patients who are undergoing and recovering from brain surgery could benefit from the device and it’s hoped that the continuous monitoring could tell if a patient is about to experience a stroke and provide an opportunity for timely intervention.
