    摘要: A gas detecting system, device and method use a variable pulse voltage waveform to increase the temperature of a detecting unit of the gas detecting system so it reacts with gas molecules from a particular space, and outputs a sensing signal. A processing unit of the gas detecting system then performs calculations on the sensing signal, such that an analysis unit may determine the presence of a target gas in the particular space, and further the composition and concentration of the target gas within the particular space, thus providing a detection that is accurate, rapid and convenient.

    摘要: A pulse-type gas concentration measurement system and a method of pulse-type gas concentration measurement in a specific environment. When the sensor is located at a specific position, a variable pulse-modulated voltage is sent to the sensor, so that the sensor outputs a first signal to the processing device. The processing device compares the first signal to the chemical matter characteristics signals to determine the composition and concentration of respective constituents in the gas, and determines a detection voltage according to the first signal. Then, a square-wave pulse with the detection voltage is sent intermittently to the sensor, so that the sensor outputs a second signal to the processing device. The processing device compares the second signal to the chemical matter characteristics signal to determine the concentration variation of each respective constituent of the gas.

    摘要: The present invention provides a biochip substrate used for immobilizing biomaterials, which has a matrix and at least one metal oxide thread-like nano-object formed vertically on a surface of the matrix. The metal oxide thread-like nano-object is employed for immobilizing the biomaterial onto the matrix of the chip substrate directly, without complicated immobilizing processes by using cross-linking agents or curing agents, and thereby simplifying the process of fabrication. Arrangement as such makes it suitable for purification of a biomaterial. On the other hand, the metal oxide thread-like nano-object characterized by having an enormous surface area is suitable for fabricating immunosensor chip and capable of maintaining high activity and reactivity of biomaterials, so as to increase speed and yield of reactions.
