A lab-on-chip system comprises an antenna and a communications subsystem to wirelessly transmit information from the lab-on-chip system. The communications subsystem may also receive information, data or instructions from an off-chip system or device. The lab-on-chip system may comprise a passive power subsystem coupled to an antenna to wirelessly receive power in the form of an electromagnetic field, which provides electrical power derived therefrom to at least one other subsystem of the lab-on-chip system.
