| Aug 6, 2020 at 9:24 | comment | added | Sneaky Puffin | I understand now! makes sense, yeah, I would probably scrap the inductive sensor as they are big. A hall effect / Reed switch might be the way forward If you really want to go the magnetic route. If you are already wearing magnetic socks that may be conductive?, I think it would be possible to create open/close a circuit from the persons foot through the ground metal plate and detect this from an Arduino, that would give you instantaneous detection of contact. | |

| Aug 6, 2020 at 9:18 | comment | added | Michael Hirschler | @JackSoldano at my sport (Taekwondo) we're wearing magnetic socks for detecting impact on vests for triggering a point (see olympic sports). The idea was to re-use these socks, so any athlete can test his speed on leaving the floor plate, and hitting a target. Maybe simple tactile buttons may do also - but I'm not an engineer, so I can't think about how to use them, without destroying them :-D I need to read some books about this topic, an hall-/inductive-sensors (and reed switches), too. | |

| Aug 6, 2020 at 8:50 | comment | added | Sneaky Puffin | @Michael Hirschler (OP) Out of curiosity why do you need the solution to be magnetic? I'm struggling to visualise the setup you described and why you wouldn't consider pressure sensors or a simple tactile button to detect when the leg in in contact with a surface? I'm just not certain if the Hall Effect sensor with give you a clean and constituent reading compared to other potential solutions. Deepening on the setup you may even be able to use the metal plate and leg as a large switch, closed when in contact & open at the moment of "Take Off". Just spit balling some ideas :) | |
