Any component that can make small taps?

I'm trying to make a device that can tap my hand in 9 different locations.
(I'm experimenting with tactile memory).

It doesn't need any force behind it, just enough to feel it.
So obviously, the device needs to be small. I imagine, the size of a glove or watch.

Anyways, this obviously means I can't use 9 motors (one for each motor driven actuator).

Are there any components (either mechanical, magnetic, or electric) that can simulate touch?
Maybe some piezo method?

Automotive fuel injector ? They are relatively low cost, simple.

May have to cut away the plastic to expose end of piston.
