1. A sensor insertion tool for inserting a sensor through intact skin without a cannula or trocar, comprising:
a channel guide assembly, comprising
a channel guide, and
a channel guide cover, wherein the channel guide and the channel guide cover together form a channel guide assembly channel;
a motive force assembly to store and release energy, comprising
a motive force member,
a hammer channel separate from and non-contiguous with the channel guide assembly channel, and having a curved portion,
a hammer extending through the channel guide cover into the channel guide assembly channel, and
a hammer pin coupled to and extending transverse from the hammer, the hammer pin configured to extend from the hammer into the hammer channel and move along the curved portion of the hammer channel to guide the hammer to strike a sensor subassembly positioned within the channel guide assembly channel;
a cocking assembly coupled to the motive force assembly to load energy into the motive force assembly; and
a trigger assembly having a trigger member coupled to the motive force assembly to release stored energy in response to actuation of the trigger member.
