Stents are vital to clearing blockages in blood vessels, but the low-tech devices offer no feedback as to whether they’re working. A recent Medgadget article discussed a new type of ‘smart’ stent that aims to improve the way patients with cardiovascular issues monitor their hemodynamic data.

They operate without the use of wires or batteries, and are powered via a wireless energy transfer system that employs magnetic fields.
