I've tried the Duet 3D mechanical filament sensor (uses a hobbed gear and a magnetic encoder) worked great until the assembly shifts and the magnet ends up slightly too far away from the encoder. But detects and monitors filament movement, so can detect runout and underfeed. Would work great if it had a metal housing.
They are working on a laser (mouse type sensor) version but so far I'm not sure where they are with it.
I have to say if someone could design a very reliable monitor I'd use one. When I was beta testing the sensor it caught 3 genuine problems (2 blocked nozzle) and one snagged reel. I managed to fix the snagged reel and resume, but had to dismantle the hotend for the blocked nozzles and couldnt resume.

We are still working on both sensors. The rotating magnet one is more accurate. The printed assemblies we used for the prototypes are not suitable for mass production, so we have teamed up with another company that has the experience we lack in manufacturing mechanical assemblies. The laser sensor is less accurate but still entirely adequate for detecting loss of filament motion, so we are having 100 manufactured to give interested users a chance to try them and tell us what they think.

They are not available yet, but we are having a small run of the laser one manufactured at present.

No one has cracked this yet as filament isn't necessarily round. You'd need a sensor that can detect cross sectional area and movement.
