Engineers at the University of California San Diego
have developed a powerful new tool that monitors the electrical
activity inside heart cells, using tiny “pop-up” sensors that poke
into cells without damaging them. The device directly measures the
movement and speed of electrical signals traveling within a single
heart cell—a first—as well as between multiple heart cells. It is
also the first to measure these signals inside the cells of 3D
tissues.
‘Pop-up’ electronic sensors could detect when individual
heart cells misbehave
