DEVICE FEATURES AND DESIGN ELEMENTS FOR LONG-TERM ADHESION

There is provided an electronic device for long-term adhesion to a mammal, the device comprising: a flexible first wing and a flexible second wing extending laterally from a housing without overlapping, wherein each wing includes a hinge portion adjacent the housing; a first electrode positioned on the bottom surface of the first wing and a second electrode positioned on the bottom surface of the second wing, the electrodes electronically connected to a rigid physiologic data collection circuit; an adhesive layer on the bottom surface of each wing, the adhesive layer providing adhesion to the surface of the mammal; and a floating section forming a water-tight enclosure and comprising the rigid physiologic data collection circuit, the floating section configured to float above the surface of the mammal in response to movement of the mammal; wherein the rigid physiologic data collection unit extends along only a portion of the distance between the electrodes.
