Tailor-made medical devices could give a more detailed picture of cardiac health and may be better at predicting and preventing problems.
Just right: An array of sensors is embedded in a material designed to fit a beating heart perfectly. It’s a poetic fact of biology that everyone’s heart is a slightly different size and shape. And yet today’s cardiac implants—medical devices like pacemakers and defibrillators—are basically one size fits all. Among other things, this means these devices, though lifesaving for many patients, are limited in the information they can gather.
Researchers recently demonstrated a new kind of personalized heart sensor as part of an effort to change that. The researchers used images of animals’ hearts to create models of the organ using a 3-D printer. Then they built stretchy electronics on top of those models. The stretchy material can be peeled off the printed model and wrapped around the real heart for a perfect fit. … (Read more)
