Abstract:Abstract—Efficient droplet routing is one of the key approaches for realizing fault-tolerant microfluidic biochips. It requires that run-time diagnosis and fault recovery can be made possible in such systems. This paper describes a droplet routing technique for a fault-tolerant digital microfluidic platform. This technique features handling of many microfluidic operations simultaneously and uses on-chip sensors for diagnosis at run-time.
Once a fault is detected during the droplet routing, recovery procedures will be started-up immediately. Faulty units on the chip will be marked and isolated from the array so that the remaining droplets can still be routed along a fault-free path to their destinations. This method guarantees a non-stop fault-tolerant operation for very large microfluidic arrays.
