Testing the piezoelectric properties of polymer-based biocomposites for biomedical applications requires a combination of electrical, mechanical, and material characterization techniques. One of the most common methods is using a piezometer, such as a Berlincourt meter or quasi-static d₃₃ meter, to apply dynamic or low-frequency force and measure the charge output. For thin films, bending mode tests or interdigitated electrodes (IDEs) can evaluate lateral piezoelectric responses. Piezoelectric force microscopy (PFM) is highly effective for nanoscale mapping of piezoelectric activity, while conductive atomic force microscopy (c-AFM) can measure current generation under localized stress. Dynamic mechanical testing with synchronized electrical measurements, such as tensile or bending tests with attached electrodes, provides insight into strain-induced voltage or current output. Impedance spectroscopy helps analyze dielectric behavior and electromechanical coupling, while polarization-electric field (P-E) hysteresis measurements, using Sawyer-Tower or PUND techniques, assess ferroelectric contributions. Structural characterization via XRD, FTIR, or Raman spectroscopy confirms the presence of piezoelectric phases (e.g., β-phase in PVDF). For biomedical validation, in vitro biocompatibility tests—such as cell viability assays (MTT, Live/Dead staining), mechanical compatibility checks, and degradation studies—ensure the material’s suitability for physiological environments. Reliable testing requires controlled conditions, uniform sample preparation, comparison with reference materials, and statistical validation for reproducibility. A multi-technique approach combining PFM, dynamic electromechanical testing, and impedance analysis is recommended for accurate assessment of piezoelectric performance in biomedical composites.
