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...
