摘要： The present invention discloses a flexible probe structure comprises at least one electrode using a CNT layer as the electrode interface. The CNT layer disposed on the electrode surface is processed with an UV-ozone treatment to form a great number of carbon-oxygen functional groups on the surface of CNT. The carbon-oxygen functional groups can greatly reduce the interface impedance of the electrode and the biological tissue fluid. Thereby, the measurement can achieve better quality. The present invention also discloses a method for fabricating a flexible probe structure, which comprises steps: preparing a flexible substrate; forming a conductive layer on the flexible substrate, and defining an electrode, a wire and a metal pad on the conductive layer; forming a CNT layer on the electrode; forming an insulating layer on the conductive layer to insulate the wire from the environment; and processing the CNT layer with an UV-ozone treatment.

摘要： The present invention provides an analog to digital converter by using an exponential-logarithmic model. The exponential-logarithmic analog-to-digital converter includes an exponential circuit which acquires an analog input voltage and generates an analog output voltage that is an exponential function of the input voltage. A positive feedback circuit that succeeds the exponential circuit exhibits a natural logarithmic characteristic. A comparator is connected to the positive feedback circuit to compare an output voltage of the positive feedback circuit with a reference voltage. Via the exponential-logarithmic conversion technique, the time interval or pulse produced by the positive feedback circuit is a linear function of the magnitude of the input voltage. Based on the comparator output, a counter is employed to translate the analog input signal to its digital representation.
