Tiny Diamond Compass Peers Inside Batteries ⚡ экспресс
Original: "Sensitive endoscopic diamond magnetometer for non-contact sensing in confined environments"
A miniature diamond sensor, like a tiny compass, effortlessly finds currents inside batteries without opening them or needing bulky shielding.

A tiny diamond, thinner than a pen tip, was turned into an ultra-sensitive magnetic sensor. It picks up magnetic field fluctuations inside a working battery and shows where current flows. Now you can check batteries without taking them apart and without bulky interference shielding — just a slim probe.
🎯 These sensors are already being tested to record nerve impulses: they sense the ultra-weak magnetic fields that neurons create.
🎬 This device is like a tricorder from Star Trek — a portable scanner that sees the internal structure of objects.
