Manu Prakash : Research : Bubble Logic : Synchronizer Universal Logic Nonlinear bubble interactions by hydro-dynamic force fields are exploited to build universal logic gates operating at low Re number in newtonian fluids. Microfluidic memory Bistable one-bit bubble memory for storage of both information and chemicals at the same time. Bubble circuits Bubble logic devices can be cascaded to form numerous digital circuit elements like ring oscillators, counters. Bubble synchronization Non-linear fluidic ladder networks are used to synchronize two streams of bubbles, thus correcting any timing error. Bubble modulator Bubbles can be generated on demand to encode information in a train of bubbles.  Home Microfluidic bubble synchronizer implemented using a non-linear ladder network. The device geometry passively synchronizes bubbles from two different streams, thus acting as a timing restoration device for error correction. The image on the left was generated by overlapping snapshots of a movie with time stamp of a bubble depicted by the fading. The flow of bubbles is from left to right.   Image Gallery Movies © 2007-2008 Last Updated : 8 Feb. 2007
