A low power, portable, and secure Bluetooth™ sensor system has been designed and its performance has been evaluated. Light weight, small size, high interference immunity and interoperability with a personal area network are fundamental characteristics in designing the sensor system so the architecture has been implemented adopting an FPGA and a Bluetooth™ module. The design analysis shows the possibility to transmit continuously analogue signals with a high level of security. At low sampling rates, the adopted solution offers low power consumption and consequently battery with lower capacity can be adopted, minimizing the sensor system weight. With higher sampling rates, the system equipped with a FPGA offers the best architectural solution and performance. Therefore, Bluetooth™ can be satisfactorily adopted in many different applications: in the example reported in the paper, it is used for monitoring critical parameters, such as vital signs in patients having serious pathologies.
