Summary: This study quantifies the influence of circuit capacitance (C) on the measurement results of PVDF piezoelectric sensors. The voltage output models in charge mode and current mode are established and verified. It is found that the influence of C on the output voltage is independent of PVDF area, piezoelectric constant, and loading rate in current mode, while in charge mode, it is determined by the ratio of C to total capacitance.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.
