1. A sensing system for physiology measurements of blood pressure or pulse wave velocity, comprising:

  • a transmission end including a measuring signal generating module having one or more overshoot and undershoot wave generating circuits with each overshoot and undershoot wave generating circuit generating a measuring signal according to a Pulse Width Modulation (PWM) signal, and a transmitting antenna module having at least one transmitting antenna with each transmitting antenna emitting the measuring signal to a target object, wherein the measuring signal has a characteristics of a pulse wave, and overshoot and undershoot waves are also on the pulse wave;

    a receiving end having a plurality of receiving antennae with each receiving antenna receiving a reflected signal reflected by the target object; and

    a plurality of signal analyzing modules included in a plurality of sensors to generate a plurality of object active state signals by analyzing the reflected signal from the each receiving antenna, then transmit the plurality of object active state signals simultaneously or non-simultaneously to a digital signal processor,wherein the measuring signal is in a form of a radiation capable of being reflected from a physical body having blood flowing therein.
