The functions of the laminates used in the sensor were reservoirs, mixing, reaction, and detection functions. These are the first known devices that incorporate micropumps with multiple levels of functional laminates. We also have developed processes for cutting microstructures into commercially available green ceramic tape so that, when bonded, microchannels can be produced in the body of the solid ceramic device. A sample with bi-directional thermal conductivity was fabricated using copper and stainless steel laminates. Figure 2 shows a cross section of a Cu-Stainless Steel laminate.
Work is currently ongoing to determine the thermal conductivity of the laminated specimens.
