Engineering Stimuli-Responsive Material Solutions

Protecting and Enhancing the Performance of our Physical and Human Assets

Our Purpose

To safeguard and enhance the capabilities of our structural and human assets by designing stimuli-responsive materials coupled with novel interrogation, modeling, and analytical methods

We are the Active, Responsive, Multifunctional, and Ordered-materials Research (ARMOR) Laboratory at UC San Diego, led by Prof. Ken Loh. We conduct fundamental research, advance innovative ideas and technologies, and prototype new sensing and actuation systems. Our work spans the broad spectrum of technology readiness levels (TRL) of relevance to both civilian and military sectors.

  • Advanced manufacturing

  • Bio-inspired material systems

  • Composites and nanocomposites

  • Damage characterization & structural health monitoring

  • Human health and performance sensing

  • Multifunctional materials & structures

  • Noncontact nondestructive sensing

  • Soft actuators & robotics

  • Smart infrastructure materials

  • Stimuli-responsive materials

  • Tomographic algorithms & methods

  • Wearable sensors and systems

Our physical structures and human assets are susceptible to different types of degradation and damage that can adversely impact their performance. We are not only motivated to develop new technologies that can characterize or mitigate the onset of damage and offer effective countermeasures, but we also seek to enhance and augment their functionality, safety, and performance.

Prospective Applicants:

All undergraduate and graduate students interested in joining the ARMOR Lab should contact Prof. Loh (by e-mail: with your CV or resume and any other supporting materials. For more details, please visit the "Apply" page.

There are no post-doctoral positions available at this time.
