In this paper, a novel-structured electrochemical sensor array with five disk working electrodes, one arc counter electrode and one reference electrode is introduced. The array is fabricated by micro-electro-mechanical system (MEMS) technology. The radii of the disk working electrodes are 400 Pm and 500 Pm while the distance between the working electrodes and counting electrode is 100 Pm. The counter electrode is composed of difference arc rings. The radian of the arc rings ranges from S to 11S/6 while the radius ranges from 100 Pm to 200Pm for different chips. The arrays are characterized by cyclic voltammetry in the presence of the redox probe ferrocenemethanol (FcM). It is found that the peak current has a biggest value between 3S/2 and 5S/3 at the same radius of arc rings. The peak current increases along with the increasing of the radius of the arc rings. For working electrode in same size, the best design has the peak current 35% higher than the smallest peak current. An optimal design of the high sensitivity electrochemical sensor is found.

Miniature electrochemical sensors can be economically produced by thick-film technology. An area of working electrode and an electrode topology design is the important parts of design optimization of electrode system. The design of standard thick-film electrode construction is limited (2-D construction, substrate dimensions, resolution, paste cannot be used fully in this case and larger electrode area can be making by 3-D structure only. One of resolutions is unconventional method. The increase of electrode surface by unconventional method ball and wire bonding is discussed in this paper. The sensors with standard TFT gold surface of working electrode and increased surface of working electrode, e.q. by gold bonds and gold wires, was tested and compared. The practical measurement was made in a model reversible system, alkaline solution mixture of potassium ferricyanide and potassium ferrocyanide, and in solution with heavy metals.The first results show that the thick-film electrochemical sensors with standard gold surface of working electrode have lowest output current signal than sensors with new electrode configuration. The new designed sensor with modified surface by gold wires shows is one of the best results by all types of measured sensors. I ntroductionThick-film sensors are used in various human activities (food industry, agricultural industry, automobile industry, -film technology (TFT) is low price and small scale batch production [1]. At present time the thick-film technology are used as a tool of preparation of very small electronic details by SMT [2], high reliability applications and nonconventional applications [3], especially sensors. Thick-film sensors are often simple, cheap, sufficiently sensitive and accurate, with good mechanical and electrical properties.Technology of thick-film electrochemical sensors has grown from classical TFT materials [1], [2]. The application of thick-film technology to chemical sensors [4] and biosensors [5] is complicated and it is still in the intensive research and development, [6]. Various measurement systems for optimization measurement on TFT chemical sensors are developed and made [7]. Generally, current output signal of thick-film electrochemical sensor is dependent on [8], [9], [10]
