Analyzing threshold pressure limitations in microfluidic transistors for self-regulated microfluidic circuits [PDF]
, 2014 This paper reveals a critical limitation in the electro-hydraulic analogy between a microfluidic membrane-valve (mu MV) and an electronic transistor. Unlike typical transistors that have similar on and off threshold voltages, in hydraulic mu MVs, the ...
