1. An electronic device for monitoring physiological signals in a mammal, the device comprising:
- a plurality of flexible wings extending laterally from a rigid housing, each flexible wing configured to conform to a surface of the mammal and comprising a lower substrate layer, an upper substrate layer, and a bottom surface comprising a long-term adhesive, the long-term adhesive configured to adhere to the skin of the mammal;
wherein the plurality of flexible wings comprise a first material and the rigid housing comprises a second material, the second material more rigid than the first material;
a hardware processor housed within the rigid housing, the rigid housing configured to prevent deformation of the hardware processor in response to movement of the mammal;
a flexible electrode embedded within each flexible wing, each electrode configured to provide conformal contact with a non-planar surface of the skin of the mammal during movement of the mammal;
an electrode trace positioned between the upper substrate layer and the lower substrate layer, the upper substrate layer comprising a rim extending horizontally outward beyond the lower substrate layer, the rim being thinner in a vertical plane than an adjacent portion of the flexible wing and configured to reduce edge-lift of the flexible wing from the skin of the mammal; and
wherein each electrode trace extends outward from the rigid housing, each electrode trace conforming to an upper surface of a flexible electrode, the electrode traces and the flexible electrodes configured to remain conformal with the skin of the mammal during bending of the skin.
