|Remote Controlled Valves for Flow Control in LTCC-Based Microfluidic Devices|
|Keywords: Microfluidics, Low Temperature Cofired Ceramic (LTCC), Hydrogel|
|Microfluidic systems are attractive for a number of Lab-on-Chip (LOC) and micro-Total Analysis System (uTAS) based applications. However, the overall complexity and level of integration of these devices is limited by need to have a significant number of off-chip mechanical or pneumatic components; particularly in the area of fluid flow control and pumping. Hydrogels posses a number of interesting properties and can be tailored to respond to a wide different external stimuli. In this work, nanocomposite hydrogels have been developed which respond to alternating magnetic field (AMF). These nanocomposite hydrogels have been optimized for integration into an LTCC based microfluidic system to achieve remote control (RC) of on-chip fluid flow without the requirement for external valves or solenoids. The integration and remote operation of RC hydrogel valves in LTCC microfluidic devices will be presented.|
