Graphene Patch Affixes to Heart for Pacemaking
Researchers at Northwestern University and the University of Texas at Austin have developed a thin and flexible graphene “tattoo” that can be affixed to the outside of the heart, and which can monitor heart rhythms and apply corrective...

Scientists Grow Electrodes Inside The Body
Researchers at Linköping University in Sweden have developed a method whereby the body can ‘grow its own’ electrodes. The minimally invasive technique involves injecting a hydrogel that is laden with enzymes into target tissues. The...

Patient-Specific Soft Robotic Heart Replicas for Treatment Planning
Researchers at MIT have developed soft robotic heart replicas that closely match the anatomy of real people. The researchers used medical images of patient hearts to construct computer models that are suitable for 3D printing. Once printed with...

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...

Battery-Free Light-Powered Pacemaker Now a Reality
Researchers at the University of Arizona have developed a battery-free light-powered pacemaker that uses optogenetic stimulation of cardiomyocytes to achieve heart pacing. With conventional pacemakers, the leads of the device are anchored into...

FDA-Approved At-Home Spirometer: Interview with Charvi Shetty, Co-Founder and CEO at Aluna
The COVID-19 pandemic has put lung health firmly in our minds. For those with chronic lung diseases, such as asthma and COPD, an important way to keep track of lung health is to use a spirometer to measure how well air can move in and out of...

Soft Robot Grows Like a Plant to Travel Through Tight Spaces
At the University of Minnesota, researchers have developed a soft robotic system that can ‘grow’ like a plant. The mechanism allows it to travel through difficult-to-access areas, such as the tortuous gastrointestinal tract or vasculature....

Silicone Heart Models Heart Failure
Scientists at the Royal College of Surgeons in Ireland and partners at the National College of Art and Design in Dublin have developed a silicone heart model that is intended to model heart failure with preserved ejection fraction. The device,...

Biosynthetic Trilayered Ventricle Pumps Blood
Biomedical engineers at the University of Toronto have developed a method to create a small-scale biosynthetic left ventricle that can pump blood within a bioreactor. While the construct is too small to act as replacement for a human heart, it...
