1. A tissue penetration device, comprising:
- a penetrating member driver;
a cartridge;
a plurality of penetrating members integrated with the cartridge, each of penetrating member coupled to the penetrating member driver when advanced along a path into a tissue target; and
a penetrating member position sensor coupled to a processor, the processor including a memory that includes stored information of (i) a distance of a penetrating member tip from a target tissue, (ii) acceleration and displacement of the penetrating member; and
(iii) a start position of the penetrating member, the processor using the stored information to calculate depth of penetration of the penetrating member anda feedback loop coupled to the penetrating member position sensor.

Abstract
A tissue penetration device includes a penetrating member driver and a cartridge. A plurality of penetrating members are integrated with the cartridge. Each penetrating member is coupled to the penetrating member driver when advanced along a path into a tissue target. A penetrating member sensor is coupled to the plurality of penetrating members. The penetrating member sensor is configured to provide information relative to a depth of penetration of a penetrating member through a skin surface.
