Described herein is a lapel adaptor for use with a physiologic sensor pod having a housing including a top surface, a bottom surface, a peripheral surface, a groove extending around the peripheral surface, and a pair of electrodes spaced apart from one another on the bottom surface. The lapel adaptor includes a first portion comprising an elastic ring including an opening having an inner circumference slightly smaller than an outer circumference of the groove extending around the peripheral surface of the sensor pod housing. The lapel adaptor also includes a second portion having a pair of magnets spaced apart from one another by substantially a same distance as a distance between the pair of electrodes on the bottom surface of the sensor pod housing. The lapel adaptor further includes a third portion that enables the first and second portions of the lapel adaptor to be folded toward one another.
