A device includes a pliable membrane, a sensor module and a communication module. The pliable membrane includes a semi-rigid structural member. The membrane is configured to conform to a tissue surface. The structural member is configured to retain the membrane in a particular shape corresponding to the tissue surface. The sensor module is coupled to the membrane. The sensor module is configured to generate an electrical signal corresponding to a physiological parameter associated with the tissue surface. The communication module is coupled to the membrane. The communication module is configured to receive the electrical signal and wirelessly communicate data corresponding to the electrical signal with a remote device.
