In　recent　years,　energy　harvesting　technologies,　which　can　scavenge　many　kinds　of　energies　from　our　living　environment　to　power　micro/nanodevices,　have　attracted　increasing　attention.　However,　remote　energy　transmission,　flexibility　and　electric　waveform　controllability　remain　the　key　challenges　for　wireless　power　supply　by　an　energy　harvester.　In　this　paper,　we　design　a　new　infrared-driven　non-contact　pyroelectric　generator　for　harvesting　heat　energy,　which　avoids　direct　contact　between　the　pyroelectric　generator　and　heat　source　and　realizes　remote　energy　transfer　exploiting　the　photothermal　and　penetrability　of　infrared　light.　The　output　voltage　(under　the　input　impedance　of　100　MOhm)　and　short-circuit　current　of　the　pyroelectric　generator　consisting　of　a　CNT/PVDF/CNT　layer　(20　mm　x　5　mm　x　100　mu　m)　can　be　as　large　as　1.2　V　and　9　nA,　respectively,　under　a　1.45　W　cm(-2)　near-infrared　laser　(808　nm).　We　also　demonstrate　the　means　by　which　the　pyroelectric　generator　can　modulate　square　waveforms　with　controllable　periods　through　irradiation　frequency,　which　is　essential　for　signal　sources　and　medical　stimulators.　The　overshoot　of　square　waveforms　are　in　a　range　of　9.0%-13.1%　with　a　rise　time　of　120　ms.　The　prepared　pyroelectric　generator　can　light　a　liquid　crystal　display　(LCD)　in　a　vacuum　chamber　from　outside.　This　work　paves　the　way　for　non-contact　energy　harvesting　for　some　particular　occasions　where　near-field　energy　control　is　not　available.
