A device for measuring and displaying body parameters includes a sensor that generates a signal representing a detected body parameter, such as body fat, body water and weight, and blood pressure of an individual; a transmitter to wirelessly transmit the signal; a receiver to receiver and display the sensed measurements as well as a user’s name, time, date and temperature. The transmit antenna and receive antenna are adapted to improve the detection capability of the ground penetrating radar system. Accordingly, there is an effect that a stability of a vehicle behavior can be improved without applying any fear of insecurity to the driver.
