1. bp: Blood pressure analysis in R

   Despite the world-wide prevalence of hypertension, there is a lack in open-source software for analyzing blood pressure data. The R package bp fills this gap by providing functionality for blood pressure data processing, visualization, and feature extraction. In addition to the comprehensive functionality, the package includes six sample data sets covering continuous arterial pressure data (AP), home blood pressure monitoring data (HBPM) and ambulatory blood pressure monitoring data (ABPM), making it easier for researchers to get started. The R package bp is publicly available on CRAN and at https://github.com/johnschwenck/bp .

   We present a study on the development of piezoelectric nanofibers for wearable hemodynamic sensing by incorporating nanoparticle doping of piezoelectric nanofibers. The composite material was characterized using various techniques, including scanning electron microscopy, X-ray diffraction, and tensile test. The material was also evaluated in a custom-built pressure chamber. Achieving optimal sensor performance, the study identified 20 wt% BTO composite materials as ideal, with a peak voltage output of 0.12V. Higher concentrations presented electrospinning difficulties, compromising material consistency. Quantitative analysis through fast Fourier transform (FFT) and digital bandpass filtering precisely isolated physiological signals, notably respiration and heartbeat, with the sensor demonstrating accurate detection capabilities at frequencies of 0.2, 1.35, and 2.65 Hz, indicative of the targeted physiological processes. The results demonstrate a promising potential for the use of these materials in future wearable hemodynamic sensing applications.
