Does anybody know how I would make a soft foam sword detect a hit on a vest? This is for a dueling game, sort of like fencing, with nerf weapons. I'm hoping to eventually create a system using an arduino.
These are some sensors I've looked into already but I haven't found enough similar projects to know for sure that they would be appropriate:
Membrane relay switches this would require no hardware in the weapon. Can detect the intensity of a hit. but it could be detected by any kind of contact, even a crinkling vest.
Magnetic contact switches Magnets inside of the sword would be detected when in close proximity to the vest. would make the weapon heavier, possible need for wiring between weapon and vest, difficulty getting the magnetism through a foam weapon.
Voltage Divider foam sword needs a conductive material. Possible electrocution. Possible need for wiring between weapon and vest.
Frequency generator & microphones Emit a supersonic frequency that is detected when in proximity of the vest. Difficulty getting the frequency through a foam weapon, possibility of water damage to microphones. Interference between many people using the same process.
