Tel Aviv University Researchers Develop Breakthrough Fluidic Computing System
Tel Aviv University researchers have developed a fluidic computing system that performs mathematical operations and logic using liquids in microchannels within flexible materials.
Researchers at Tel Aviv University have developed an innovative fluidic computing system that performs mathematical operations and digital logic using liquids flowing through microscopic channels in a flexible material. Led by Roi Almog and Prof. Bat-El Pinchasik from the School of Mechanical Engineering and the Center for Physics and Chemistry of Living Systems, the study was published in the prestigious scientific journal Advanced Science.
In digital computers, information flows through logic gates as electrical signals representing binary states of zeros and ones. In the new system, researchers translated this electronic framework into a fluidic language. The presence of liquid at a specific point represents a "1", while its absence denotes a "0". Inputs are introduced through simple mechanical presses on the channels from various directions, altering flow paths to execute logic operations using only liquid dynamics. Capillary action drives the fluid without requiring external pumps or power sources.
The system utilizes open channels where gas can safely escape, preventing blockages caused by bubbles, and was demonstrated through controlled acid-baking soda reactions generating carbon dioxide. The researchers successfully constructed basic logic gates such as AND, OR, and XOR, and even combined them to execute binary addition. While currently slower than electronic computing, this passive, energy-efficient approach integrates processing directly into the material, paving the way for advanced lab-on-a-chip applications, microfluidic diagnostics, and automated chemical testing.
