碩士 === 國立臺北科技大學 === 機電整合研究所 === 104 === The goal of this research is to develop low power consumption、low cost and combine wireless wearable circuit design. Glucose, we designed a set of continuous glucose measurement device to measure the variation glucose changed on the human body. On the circuit design, we used Potentiostat to measure the glucose and filter circuit to eliminate the noise generated by the electrochemistry, also probing the temperature’s affection to glucose enzyme. For deferent kinds of glucose specimen, we used Bluetooth to set up the corresponding parameters, in respond to those parameters; we could transfer the voltage measure from the glucose sensor into data. Foot pressure, using the principle of the pressure to change the distance of the electrode, by using capacitance sensing chip to measure capacitance value, then transmission through the Bluetooth and display it on the mobile device, because the circuit has to install at the bottom of the insole, so we need to use flexible circuit board for the circuit and minimize the component, therefore, we didn’t use the existing module, instead, we design the oscillator and antenna matching by ourselves to reach the goal of minimize the component.
