With　the　advancement　of　industrial　automation,　vibrational　energy　generated　by　machinery　during　operation　is　often　underutilized.　Developing　efficient　devices　for　vibration　energy　harvesting　is　thus　essential.　Triboelectric　nanogenerators　(TENGs)　based　on　spring　and　cantilever　beam　structures　show　considerable　potential　for　industrial　vibration　energy　harvesting;　however,　traditional　designs　often　fail　to　fully　harness　vibrational　energy　due　to　their　structural　limitations.　This　study　proposes　a　triboelectric　nanogenerator　(TENG)　based　on　a　crank-rocker　mechanism　and　a　spring　cantilever　structure　(CR-SC　TENG),　which　combines　a　crank-rocker　mechanism　with　a　spring　cantilever　structure,　designed　for　both　energy　harvesting　and　self-powered　sensing.　The　CR-SC　TENG　incorporates　a　spring　cantilever　beam,　a　crank-rocker　mechanism,　and　lever　amplification　principles,　enabling　it　to　respond　sensitively　to　low-frequency,　small-amplitude　vibrations.　Utilizing　the　crank-rocker　and　lever　effects,　this　device　significantly　amplifies　micro-amplitudes,　enhancing　energy　capture　efficiency　and　making　it　well　suited　for　low-amplitude,　complex　industrial　environments.　Experimental　results　demonstrate　that　this　design　effectively　amplifies　micro-vibrations　and　markedly　improves　energy　conversion　efficiency　within　a　frequency　range　of　1-35　Hz　and　an　amplitude　range　of　1-3　mm.　As　a　sensor,　the　CR-SC　TENG＇s　dual-generation　units　produce　output　signals　that　precisely　reflect　vibration　frequencies,　making　it　suitable　for　the　intelligent　monitoring　of　industrial　equipment.　When　placed　on　an　air　compressor　operating　at　25　Hz,　the　first-generation　unit　achieved　an　output　voltage　of　150　V　and　a　current　of　8　mu　A,　while　the　second-generation　unit　produced　an　output　voltage　of　60　V　and　a　current　of　5　mu　A.　These　findings　suggest　that　the　CR-SC　TENG,　leveraging　spring　cantilever　beams,　crank-rocker　mechanisms,　and　lever　amplification,　has　significant　potential　for　micro-amplitude　energy　harvesting　and　could　play　a　key　role　in　smart　manufacturing,　intelligent　factories,　and　the　Internet　of　Things.
