Patent attributes
Apparatus, electronic device, system and method comprising a first element (102) configured to receive a first signal and convert the first signal to a second signal, a second element (104) configured to relay the second signal to a third element (106, 108), the third element (106, 108) being configured to convert the second signal to a third signal and to send the third signal; wherein the first element (102) is configured to convert the first signal to the second signal in such a way that the conversion is dependent on the physio-chemical structure of at least part of the first element (102). In some embodiments the first element comprises a photoacoustic sensor comprising at least one graphene layer, the second element comprises a mechanical wave transmission line, and the third element comprises carbon nanotube antennas.
