Abstract 

A new wearable sensing system of respiration rate based on a piezoresistive FlexiForce sensor has been developed. The 3D casing of the system has been designed and printed with a 3D printer. The design of the casing has a direct impact on sensor accuracy. The casing was designed to house all elements of the sensing system in a compact way: microcontroller, battery, conditioning circuit, Bluetooth module and battery charger. The sensing system was validated with twenty-one subjects using a metronome as a reference. The sensor was worn in the chest at the level of the diaphragm through a chest strap. Six different values of breaths per minute (BPM) were assessed: 10, 12.5, 15, 17.5, 20 and 22.5 BPM. Subjects were requested to perform one full minute of breathing for each reference value at the rhythm of the metronome, for five different activities (sitting, sitting and moving, standing, standing and moving, and walking). This dataset includes the raw voltage signals recorded during the validation experiments (ADC readings expressed on bits). It is organized in twenty-one folders (1 per subject). Each folder contains thirty different text files (six reference values for each of the five positions). In total, this dataset comprises 630 files of breathing signals.
