Biobots Use Optogenetic Muscle Actuators for Movement

Researchers at the University of Illinois at Urbana-Champaign have developed centimeter-scale biobots that combine soft materials, mouse muscle tissue, and wireless electronic components. The tiny devices can be controlled remotely through optogenetics. The muscle within the devices forms an optogenetic actuator and creates movement when exposed to (Read more...)

Implantable Device Adheres to Muscle, Treats Atrophy

Scientists at the Wyss Institute for Biologically Inspired Engineering at Harvard have developed a mechanically active gel-elastomer-nitinol tissue adhesive, otherwise known as MAGENTA. The implantable device functions as a soft robot, and it can be adhered to the outside of a muscle. When an electrical charge is applied to the device, a spring ins (Read more...)

Device Measures Hemoglobin More Accurately in Dark Skin

Researchers at the University of Texas at Arlington, in collaboration with Shani Biotechnologies, a local firm, have created a point-of-care device that can accurately measure hemoglobin levels and perform pulse oximetry in individuals with dark skin. At present, methods to determine hemoglobin levels at the point of care, such as pulse oximetry, a (Read more...)

Electrospun Construct Mimics Elasticity of Blood Vessels

Researchers at the University of Sydney in Australia have developed an electrospun blood vessel replacement. The material contains tropoelastin, a natural precursor for elastin, a key component of blood vessel walls. Elastin is present in concentric circles in natural blood vessels and provides the elastic properties which allow them to distend sli (Read more...)

Symani Microsurgical Robotic System: Interview with Mark Toland, CEO of Medical Microinstruments

Medical Microinstruments, a medtech company with offices in Pisa, Italy and Delaware, USA, has developed the Symani Microsurgical Robot. The robotic system is designed to assist with microsurgical procedures, and it boasts a variety of advanced features to achieve this goal. These include a suite of the world’s smallest wristed surgical instr (Read more...)

Flexible Sensors Measure Fit of Face Masks

Researchers at MIT have developed a sensor system that can provide data on how well a face mask fits to a wearer’s face. The protection offered by a mask is largely dependent on how well it fits the face, but at present most face masks are one-size-fits-all and most wearers are largely unaware if their […]

Neck Sensor Helps Masked Clinicians Communicate

Researchers at Pohang University of Science & Technology in South Korea developed an auditory sensor that lets people wearing face masks, such as clinicians, to communicate more easily. The device is essentially a wearable microphone that picks up the vibrations of the skin in the neck that occur when someone talks. The researchers hope that [& (Read more...)

Novel Devices to Help Surgeons Sculpt a New Ear

At Johns Hopkins, clinical researchers have developed a set of surgical tools that allow them to more easily create a replacement ear for those born with malformed or missing ears. Currently, using cartilage harvested from the ribs, surgeons can create a new ear, but the process is difficult and requires some artistic talent to sculpt […]

Soft Robot Biodegrades Inside Body

Researchers at the City University of Hong Kong have developed a magnetic soft millirobot that can grab and release objects, and move around by rolling. The device can be controlled using magnetic fields, and consists of a biodegradable gelatin and iron oxide microparticles. The technology has significant potential as a minimally invasive drug deli (Read more...)

Granular Hydrogels for Improved Bioinks

Researchers at Penn State have developed a granular hydrogel that contains both hydrogel microparticles and self-assembling nanoparticles, and which could be highly suited for bioprinting purposes. The concept involves the nanoparticles becoming adsorbed onto the hydrogel microparticles and reversibly adhering the microparticles together, providing (Read more...)

Smart Socks Help Prevent Falls Among At-Risk Patients

Researchers at the Ohio State University Wexner Medical Center have tested the PUP (Patient is Up) Smart Socks, developed by a medtech company called Palarum, in their ability to reduce falls among at-risk patients. The socks contain pressure sensors that alert caregivers when a patient is attempting to stand up. This can include situations such [& (Read more...)

AR Headset Helps Surgeons Place Implants: Interview with Louie Vogt of Enovis Surgical

Enovis, a medtech company based in Delaware formerly known as DJO, recently announced the launch of ARVIS (Augmented Reality Visualization and Information System), an augmented reality technology that is designed to assist surgeons during implant placement in the hip and knee. The hands-free technology consists of an eyepiece that is mounted on a s (Read more...)

Tough Ultrasound-Controlled Bioadhesives

Scientists from McGill University in Canada created a technique of using ultrasound-mediated cavitation to make bioadhesives better stick to body’s tissues, including wet surfaces that are typically challenging for such materials. The new method involves ultrasound to create microbubbles within the adhesive. The bubbles burst, which then temp (Read more...)

Bacterial Microrobots Deliver Drug Payload to Tumors

Scientists at the Max Planck Institute for Intelligent Systems in Germany have developed tumor-targeting microrobots using bacteria. The team exploited the tendency of bacteria to naturally gravitate towards areas of low oxygen and low ph, which both tend to occur in the vicinity of a tumor. Once near the tumor, the bacteria aggravate the immune [& (Read more...)

TORdx LUNG Test for Donor Lung Assessment: Interview with Eric Brouwer, Chief Scientific Officer at SQI Diagnostics

SQI Diagnostics, a medtech company based in Canada, is developing the TORdx LUNG Test. The technology is intended to assist clinicians in assessing donor lungs in their suitability for transplantation. At present, clinicians typically assess donor lungs using qualitative variables, such as donor health and lung size. One of the most important facto (Read more...)

Improving Transplant Survival with Organ Preservation Tech: Interview with Dr. Anderson, CEO of Paragonix

Paragonix Technologies, a medtech company based in Massachusetts, created the SherpaPak, an FDA organ transportation device that is intended to keep donor organs safe and viable on their journey to a transplant recipient. As the viability of a donor organ can mean life or death for the receiving patient, it makes sense to take exceptional [… (Read more...)

Soft Bioresorbable Implant Controls Pain by Cooling Nerves

A team of engineers at Northwestern University led by John Rogers, the person responsible for many advances in flexible electronics, created a drug-free implant that can control pain by cooling nerves. The soft implant is intended to be wrapped around a nerve during surgical procedures that would typically involve opioid-based analgesia afterwards. (Read more...)

Magnetic Steering System for Guidewires

Percutaneous coronary intervention is an incredibly useful technique to minimally invasively investigate and treat cardiac issues, such as blockages in the coronary arteries, but it requires a significant amount of skill to perform safely and effectively.
