ABSTRACT:
Microfluidic devices having active features such as valves, peristaltic pumps, and mixing portions are fabricated to have a thin elastomeric membrane over the active features. The active features are activated by a tactile actuator external to the membrane, for example, a commercial Braille display. The display may be computer controlled, for example by simple text editor software, to activate individual Braille protrusions or a plurality of protrusions to actuate the active portions of the microfluidic device. Integral devices can incorporate the tactile actuators in a single device, but still external to the membrane.
