Electrowetting-on-dielectric (EWOD) chips have emerged as the most widely used actuators for digital microfluidic (DMF) systems. These devices enable the electrical manipulation of microfluidics with various advantages such as low power consumption, flexibility, accuracy, and efficiency. In addressing the need for low-cost and practical fabrication, pin-count reduction has become a key problem to...
In this paper, we propose a node's call-for-assistant protocol, named an event-driven mobile assistant protocol (EDMAP for short), with which when a node N is going to exhaust its energy, it calls for mobile nodes to help it to relay packets so the tasks of sensing environment or environment change and relay packets for upstream nodes can be proceeded. Experimental results show that this approach...
Recent advances of digital microfluidic biochips (DMFBs) have revolutionized the traditional laboratory procedures. By providing the droplet-based system, DMFB can perform real-time biological analysis and safety-critical biomedical applications. However, different droplets being transported and manipulated on the DMFB may introduce the contamination problem caused by liquid residue between different...
As the microfluidic technology advances, the design complexity of digital microfluidic biochips (DMFB) are expected to explode in the near future. One of the most critical challenges for DMFB design is the droplet routing problem, which schedules the movement of each droplet in a time-multiplexed manner. In this paper, we propose a fast routability- and performance-driven droplet router for DMFBs...
In this paper, we propose a contamination aware droplet routing algorithm for digital microfluidic biochips (DMFBs). To reduce the routing complexities and the used cells, we first construct preferred routing tracks by analyzing the global moving vector of droplets to guide the droplet routing. To cope with contaminations within one subproblem, we first apply a k-shortest path routing technique to...
