Best insight from top research papers
Closed-loop pressure control in microfluidics offers higher precision and accuracy compared to traditional pressure control methods. The usage of Quantitative Phase Imaging (QPI) technique in microfluidics allows for real-time detection of flowing droplets, providing a precise 3-D measurement of droplet volume as a feedback signal . Incorporating a closed-loop feedback control scheme with PID feedback control further enhances accuracy and monodispersity of on-demand droplet generation, while resisting internal or external perturbations . Another approach to improve control in microfluidic systems is the use of pressure-controlled networks, which eliminate the need for control droplets and instead use a single pump to drive switches, resulting in more reliable and robust operation . Additionally, the use of a proportional and integral (PI) controller in closed-loop control pressure-driven devices improves the dynamic characteristics and enables precise measurement and control of pressure-driven flows in microfluidic systems .

How to control pH in microfluidic devices?5 answerspH control in microfluidic devices can be achieved through various methods. One approach is to generate controlled quantities of reagents electrochemically in microdroplets confined within a microfluidic channel. Another method involves utilizing the ion concentration polarization (ICP) phenomenon to create a well-defined pH gradient in a microchannel by adjusting the proton mass transportation. Additionally, a microfluidic mixer with an integrated ion-sensitive transistor (ISFET) can be used to adjust the pH of a mixed solution by controlling the flow rates of acid and base solutions. Another technique involves reacting biofluid samples with a polymer buffering material during transfer to a sensing element, which causes protonation or deprotonation of the sample based on the pH and functional groups in the buffering material. Real-time pH monitoring and adjustment can also be achieved in microfluidic enzymatic reactors using optical pH sensors and fluidic inputs.

What is a closed-loop system in the context of behavioral studies?3 answersA closed-loop system in the context of behavioral studies refers to a system where the input and output of the system are interconnected and influence each other in a continuous feedback loop. It involves simulating and predicting behavioral performance based on memory changes or physiological data, and using this information to control the operation of an intervention system or neurostimulator. Closed-loop systems can be used for memory consolidation, product reordering, or control of spinal cord epidural stimulation. These systems can incorporate learning algorithms and analyze the development of the system over time, taking into account energy, input/output ratio, and entropy measures. Closed-loop behavioral systems can also involve chained learning architectures, where behavior is improved by temporally correlating sensor cues and learning from them in a sequential manner.
