Abstract
On-body units are provided and include a transcutaneous analyte sensor, electronic circuitry electrically coupled to the sensor, and an on-body housing having electrical contacts disposed thereon. The on-body housing comprises a substantially flat surface and a curved and convex surface opposite the substantially flat surface. Systems and methods including the on-body units are also provided. Methods for performing continuity measurements using on-body units are also provided. The methods include positioning an on-body unit (OBU) on a skin of a subject, contacting a continuity test instrument to the OBU; and performing a continuity measurement with the continuity test instrument. An AC signal may be provided across two electrical contacts, or a DC signal may be provided across two electrical contacts in opposite directions for the same amount of time. The measurement may be performed with one electrical contact, or with isolated electrical contacts.
