Research Interests: Medical devices
Monica Lin is PhD student in the UC Berkeley - UCSF Graduate Program in Bioengineering, with a research focus on medical devices. She is interested in developing sensors to address unmet clinical needs, and currently works in Dr. Michel Maharbiz's lab designing and building an electronic bandage to monitor pressure ulcers.
Monica received her B.S. in Chemical Biology with a Bioengineering minor from UC Berkeley.
Impedance Sensing Device to Monitor Pressure Ulcers [BPN714]
Chronic cutaneous wounds affect millions of people each year and take billions of dollars
to treat. Formation of pressure ulcers is considered a "never event" - an inexcusable, adverse
event that occurs in a healthcare setting. Current monitoring solutions (pressure-distributing
beds, repositioning patients every few hours, etc) are very expensive and labor intensive. In
response to this challenge, we are developing a novel, flexible monitoring device that utilizes
impedance spectroscopy to measure and characterize tissue health, thus allowing physicians to
objectively monitor progression of wound healing as well as to identify high-risk areas of skin to
prevent formation of pressure ulcers. Previous studies that examined the dielectric response of
cell suspensions and tissues have identified several distinct dispersions associated with
particular molecular-level processes that can be used to distinguish between tissue types. We are
utilizing impedance spectroscopy to detect subtle changes in tissue, enabling objective assessment
and providing a unique insight into the condition of a wound. Wireless capability can be
implemented to allow for remote monitoring. In parallel, efforts are being made to transfer this
technology onto resorbable substrates to create a device that can monitor internal wound healing
and readily dissolve after healing.
