Figure 1. Color photograph of the device (A) and a CAD render of the LCP reservoir (B).
Photograph of the fully assembled device. The white LCP reservoir is capped by the purple and gold microchip. The 3 green squares on the microchip are the suspended nitride membranes. The polyimide coated copper leads protrude from the device (A). The reservoir dimensions are 3.7 by 3.2 × 2.2 mm. The total drug payload is 10 milligrams of TMZ. The 200 μm shelf is visible on the interior face of the reservoir walls. This shelf serves a seat for the chip and as an upper boundary for drug during the loading process. A lead-way was designed in the top perimeter of the chip to allow the polyimide leads to project out from the device (B).
