Dr. Yeo's group conducts research in soft, flexible electronics, nanomaterials, and biosensors and applies discoveries to develop biomedical devices and other human-machine interfacing solutions.

The researchers are developing soft, flexible electronics using nanomaterials, biosensors, and synthetic rubber-like polymers. Their soft, bioelectronic systems are distinct from conventional electronics, which have a hard and rigid structure. These low-profile systems are designed to have better contact and interaction with human tissue, including external (skin) and internal (organs) tissue. For example, nanotechnologies enable Dr. Yeo's research group to deliver power to implantable sensors via coils less than a millimeter wide, eliminating the need for circuits and batteries. 

Used for disease diagnosis and therapeutics, these systems also have potential for human-machine interfaces, allowing signals from a human user to control external hardware and software to operate robots or construction systems. 

"I am currently working on around 20 different projects, 17 of which are biomedical devices," said Dr. Yeo. "I just founded a company with my Ph.D. students that is working to develop wearable technologies that can measure heart and lung sounds and physiological signals for patients who need to be monitored continuously. This would replace a conventional stethoscope or similar device that needs to be applied by hand. It is like a small bandage that is connected to a smart phone or tablet and will show the heart or lung function data."
