A novel piezoresistive cantilever microprobe (PCM) with an integrated electrothermal or piezoelectric actuator has been designed to replace current commercial PCMs, which require external actuators perform contact-resonance imaging (CRI) of workpieces and avoid unwanted "forest peaks" observed at large travel speed in the millimeter-per-second range. Initially, a PCM resistors for actuation (ETA) was designed, built, tested. Here, ETA can be performed Wheatstone bridge, converts mechanical strain into electrical signals by boron diffusion order simplify production process. Moreover, new substrate contact added design AC voltage supply bridge reduce parasitic signal influence via EAM (Electromechanical Amplitude Modulation) our homemade CRI system. Measurements on bulk Al sample show expected force dependence CR frequency. Meanwhile, fitting measured spectra applied based Fano-type line shape reveal material-specific signature single harmonic resonator. However, noise is greatly increased bending mode increasing viscoelastic samples. Then, unspecific peaks remaining soft samples, cantilevers (PEAs) were designed. The numbers positions optimized specific vibration modes using analytical modeling transfer-matrix method Hertzian mechanics. To confirm PEA, finite element analysis (FEA) probing Young's modulus 10 GPa performed. Close agreement achieved amplitude phase first four vertical cantilever. As important structure had have suitable doping parameters adapted boundary conditions manufacturing process newly PCM.

Abstract Self‐powered devices for human motion monitoring and energy harvesting have garnered widespread attention in recent research. In this work, we designed a honeycomb‐structured triboelectric nanogenerator (H‐TENG) using polyester cloth Teflon tape, with aluminum foil as the conductive electrode. This design leverages large surface area flexibility of textiles, resulting significant performance improvements. The H‐TENG achieves an output voltage 350 V, current 42 μA, transfer charge (Q SC ) 77 nC, maximum power 465 μW. Additionally, demonstrates ability to monitor running activities various gait patterns, providing real‐time bio‐mechanical data smart applications. introduction stacked structure further enhances by increasing contact scalability, making robust high‐performance harvester suitable advanced wearable flexible electronics.
