1. A microneedle application device for moving a microneedle array toward a target skin location, the microneedle application device comprising:
- a portion of the microneedle application device adapted for skin contact at least prior to microneedle application; and
a feedback sensor operably connected to the microneedle application device, wherein the feedback sensor is capable of generating an output corresponding to forces between the target skin location and the portion of the microneedle application device at least prior to microneedle application;
wherein the microneedle array comprises two or more microneedles each comprising a height of no greater than about 250 micrometers; and
wherein the feedback sensor comprises one or more sensor regions positioned to sense the force between the portion of the microneedle application device adapted for skin contact and the target skin location andfurther comprising an additional sensor region operably connected to a piston of the microneedle application device.
