Abstract
A spacer forming method for a biosensor that has a biosensor possessing a capillary sampling channel and electrical connecting tracks for the use of a specific portable meter. A pair of electrodes is printed on an insulating base plate to be the transducer of the electrochemical biosensor by means of the screen-printing technology. The advanced thick-film printing technology is employed to construct the spacer component of the sampling channel that precisely controls the volume of a sample solution. Therefore, the spacer forming method reduces the usage of adhesive that otherwise causes a serious problem during a continuous punching procedure. Furthermore, the embedded switch pad on the biosensor is introduced to be instead of a micro switch in a connector of the portable meter.
