A method of fabricating an elastomeric structure, comprising: forming a first elastomeric layer on top of a first micromachined mold, the first micromachined mold having a first raised protrusion which forms a first recess extending along a bottom surface of the first elastomeric layer; forming a second elastomeric layer on top of a second micromachined mold, the second micromachined mold having a second raised protrusion which forms a second recess extending along a bottom surface of the second elastomeric layer; bonding the bottom surface of the second elastomeric layer onto a top surface of the first elastomeric layer such that a control channel forms in the second recess between the first and second elastomeric layers; and positioning the first elastomeric layer on top of a planar substrate such that a flow channel forms in the first recess between the first elastomeric layer and the planar substrate.

1. A composite structure comprising: an elastomer component with a Young's Modulus between about 50 Pa and about 10 MPa including a recess and a flexible membrane portion;a substantially planar nonelastomer component sealed against the elastomer component; andan active device disposed within the nonelastomer component, wherein the active device is configured to interact with at least the membrane portion or a material present in the recess. 2. The composite structure of claim 1 wherein the active device is an optical structure selected from the group consisting of a photodiode, a fiber optic device, a fiber optic interconnect, a light emitting diode, a laser diode, vertical cavity surface emitting laser (VCSEL), a micromirror, a CMOS imaging array, a CCD camera, a waveguide, and a source or a receiver for visible, infrared, or ultraviolet regions of the electromagnetic spectrum. 3. The composite structure of claim 1 wherein the active device is an electronic structure selected from the group consisting of a resistor, a capacitor, a transistor, a chemical field effect transistor, a amperometric/coulometric electrochemical sensor, an accelerometer, a pressure sensor, a flow sensor, an electronic logic structure, a microprocessor, a chemical sensor, a strain gauge, an inductor, an actuator, a coil, a magnet, an electromagnet, a magnetic sensor, a radio frequency source, a radio frequency receiver, a microwave frequency source, a microwave frequency receiver, a radioactive particle counter, and an electrometer. 4. The composite structure of claim 1 wherein the active device is a thermal structure selected from the group consisting of a thermistor, a Peltier cooler, and a resistive heater. 5. The composite structure of claim 1 wherein the active device is an electrode that electrostatically drives the membrane portion into the recess.
