Research 

We are broadly interested in the following  technologies and their applications for wearable and implantable biomedical device systems:

  • Flexible/stretchable electronics
  • N/MEMS & Microfluidics
  • Biophotonics
  • Bio-integrated/Bio-inspired engineering

Wearable Skin-like Electronics

Conventional biomedical devices mounted on or implanted into our body are rigid, bulky, and its mechanical properties do not match with the property of the human tissue. Based on flexible/stretchable electronics technologies, our group develops soft, flexible, and stretchable devices with diagnostic and therapeutic capabilities, which can be conformally wrapped on curvilinear-shaped skin. In combination with wireless technology, it will bring enormous impact on the emerging fields of ubiquitous healthcare and personalized medicine. We are broadly interested in stretchy bio-integrated devices that integrate multiple modalities (electronics, photonics, and microfluidics).


Implantable Soft Electronics

Implantable devices have been drawing significant attentions in biomedical research for continuous monitoring of force, pressure, temperature, and electrophysiological signals inside the living subject. The implantable sensor systems must be small in size, compatible with human tissue, and sturdy enough to withstand the physical forces within the human body. Our research focus here is to develop soft, stretchable, and biocompatible sensors that will enable high spatiotemporal resolution and minimal mechanical loading that conform to the micro-geometry of tissue without creating damaging local stresses. Our particular interests are in wireless multifunctional neural probes and implantable cardiac devices.
