Abstract

Microfluidic devices and systems that include keying, registration or indication elements that communicate a functionality of the microfluidic device to the instrumentation which is used in conjunction with these devices. Indicator elements include structural indicators, electrical indicators, optical indicators and chemical indicators. Different indicator elements are indicative of different functionalities, e.g., applications, new vs. used, and the like.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A microfluidic device, comprising: 
 a body structure configured to interface with a base instrument, the body structure having microfluidic elements disposed therein; and    an indicator element fabricated into the body structure, the indicator element providing an indication to an instrument of a functionality of the microfluidic device.
