Through the use of micro-sensors a new phase of research, in which devices are becoming continuously smaller, has emerged. Such technology has been proposed as a pervasive solution to continuously monitor the physiological conditions of the body but depends on the ease of its use, that is, the job of the device would be to work without being noticed by the user. The miniaturization of sensor components and the elaboration and transmission of signals, combined with a growth in the development of materials needed to construct such devices makes using the devices effective, potentially without even noticing their presence, so that they can be used in everyday life. Among the multiple possibilities, one area of particular interest for further research in Biodesign is the notion of the wearable device. The success of wearable sensors and wearable systems resides mainly in the miniscule dimensions of the technology within a single component that makes the object have natural characteristics and a familiar feel to the user. In this paper we show a chest band for monitoring preconcerted physical parameters developed through concepts of wearability.
