I'm coming from a product design background and have very modest knowledge about electrical engineering. Please bear with me...
I'm currently drawing a small wearable device and have been looking for a physical (un)latching mechanism. The mechanism does not need to be particularly fast (<1 s), strong (<1 N), nor have a large displacement (~1 mm). The mechanism will be unlocking an object within a bracelet, and will do so rarely - probably just once.
However, the component needs to be quite small (ideal max height ~6 mm), off the shelf (manufacturing aim between 1000 and 5000 units), and be confined to the limited voltage and current from the batteries on wearable things (battery not yet defined).
I've looked at miniature solenoids, geared motors, piezo stuff. But, I feel like there's some component or clever solution I'm missing..?
(I acknowledge this as a kinda non-specific question, but it's sort of a blue pill | red pill decision at this point of development.)
