Microholes
Microholes that allow a fluid exchange between the top and bottom surfaces of the microelement array are often needed. They typically are designed to penetrate the stratum corneum of animal skin, or to penetrate some other type of membrane. Once the penetration has been accomplished, a fluid (e.g., liquid drugs) can be dispensed into the body from a reservoir in the microstructure, or in the reverse direction, a body fluid can be sampled into such a reservoir in the microstructure. The proper size and shape of the microholes depend upon many factors, and for some applications (e.g., drug delivery or body fluid sampling through human skin), several different sizes, and especially shapes, are needed.
