A biochip can obtain various types of genetic information over a short period of time and enable genetic analysis. A biochip needs temperature sensors to measure temperature. A resistance temperature detector temperature sensor chip, made of copper using a printed circuit board, was introduced in this study. A printed circuit board is readily usable for copper pattern design for the substrate of a biochip. To measure biochip resistance, we tested whether it was possible to accurately measure the temperature using resistances measured at room temperature and at 55, 72, 85, and 95°C in a water bath. However, in analyzing the results obtained, the printed circuit board based resistance temperature detector sensor was found to be inadequate for use as a biochip temperature sensor, although it showed potential for use as a general-purpose resistance temperature detector sensor.
