Comfortable body monitoring is crucial to many wearable devices. However, many traditional sensors impede wearability by their physical structure or functional requirements. This paper presents the application of a novel garment-integrated foam-based pressure sensor used for monitoring the wearer?s respiration rate. The sensor was evaluated in a torso garment during a 10-minute treadmill test. Results were accurate within one breath per minute, as compared to a standard airflow breathing test.
