The possibility of monitoring the health status of elderly people or patients undergoing home therapy leads to significant advantages in terms of cost savings and convenience for the patient. However, non-clinical application of biomedical signals acquisition requires the employment of different monitoring devices that must have, between the other characteristics, reduced size, low power and environment compatibility. The research activity concerns the development of a new t-shirt that can monitor the principal vital parameters of a person in a non-invasive manner. Such t-shirt is equipped with sensors that perform measurements avoiding a direct contact with user’s skin. It presents two subsystems. The first one is a wearable hardware, in which sensors are integrated for vital parameters acquisition. The second one is a remote monitoring station, which is connected to the Internet for telemedicine applications. The t-shirt is a useful solution for monitoring patient’s health condition directly at home. The parameters being monitored are electrocardiogram (ECG), heart rate (HR), which is derived from ECG signals through the determination of RR intervals, respiratory rate and subject three-axes motion (acceleration and position). In order to design and construct signal acquisition circuits in an efficient and simple manner, modular design concept is adopted in this research. Thus, flexible signal conditioning modules are realized and assembled together. Vital parameters can be recorded and analyzed continuously during work activities at home. The correct evaluation of these parameters allows clinical staff to assess user’s health state and to know the occurrence of dangerous events such as falls or accidental injuries at home.
