Wirelessly Powered Microfluidic Devices

详细技术说明

UC San Diego researchers have developed concepts and methods for incorporating printed integrated circuits into microfluidic devices and powering such electronic microfluidic devices wirelessly. In one example, the circuit elements (capacitors, diodes, gates, wires, and electrodes) were roll-to-roll printed on the plastic substrate containing the microfluidic structures and powering was accomplished by wireless coupling from a radio-frequency identification (RFID) reader. On-chip electrophoresis experiments, e.g., fast and effective assembly of microbead arrays and antibodies, have been performed using such a wirelessly powered device. Devices with additional functionality can be fabricated, e.g., with the integration of ring oscillators to generate AC signals for manipulation techniques based on AC-dieletrophoretic effects. Further, with incorporation of cell impedance measurement capability into the device, the data acquired can be sent back to the RFID reader via the printed antenna to realize wireless data transmission and storage.
