Abstract:
Wearable cardiovascular monitoring requires sensitive sensors and body-conforming electronics for reliable and automatic signal processing. Here, we present a fully self-contained platform that integrates a piezoelectric nanofibrous sensor with a custom flexible printed circuit board (PCB) for on-body charge amplification and filtering. Fabricated on a polyimide substrate with an ultralow bias current amplifier, the PCB preserves high-impedance piezoelectric signals for on-body signal processing. Electromechanical tests verified stable, linear performance improved by thermal annealing. System-level evaluation showed robust operation during cardiovascular monitoring, capturing radial, carotid, and seismocardiogram signals and extracting key cardiac parameters, demonstrating its potential as a practical, comprehensive, and wearable biosensing solution.

Real-time Flight Control: Embedded Sensor Calibration and Data Acquisition
Overview
Autopilot allows aircraft to be stabilized using data collected from onboard sensors that measure the aircraft’s orientation, angular velocity, and airspeed. These quantities can be adjusted by the autopilot so that the aircraft automatically follows a flight plan from launch (takeoff) through recovery (landing). Similar sensor data is collected to control all types of aircraft,...
