1. An implantable sensor for use in measuring a concentration of an analyte in a bodily fluid, the sensor comprising:

  • a body comprising an electrochemical sensing region adapted for transport of an analyte between the electrochemical sensing region and a bodily fluid, wherein the electrochemical sensing region comprises one or more electrodes, wherein the body comprises a first major surface and a second major surface, wherein the one or more electrodes are situated approximately at a center of the first major surface, wherein the electrochemical sensing region is located on a curved portion of the first major surface configured such that when a foreign body capsule forms around the sensor, a contractile force is exerted by the foreign body capsule toward the sensing region, and wherein the sensor is a subcutaneous sensor configured for implantation in a soft tissue of a host.
