Microfluidics for mechanical sensing and actuation in bio-medicine

Wearable technologies have a potential to transform healthcare by providing continuous measurements of physiological parameters. Sensors that passively monitor physiological pressure without using electronic components are ideal for wearables because they are easy to interface with the body and the external environment.  In our group, we developed a passive integrated microfluidic sensor with a novel transduction mechanism that converts small strain changes to a large fluidic volume expansion, detectable by a smart-phone camera. In my talk, I’ll talk about the advantages of microfluidics as wearable sensors and recent advances we have made in microfluidic large-scale integration design and fabrication.
