Portable sensors mimic the skin to aid the healing process of wounds

"We hope that these sensors and engineering work will help advance health applications and provide a better quantitative understanding of disease progression, wound treatment, overall health, disease surveillance and surveillance. fitness, etc., "said Matthew Brown, PhD student at Binghamton University.

Biosensors are badytical devices that combine a biological component with a physico-chemical sensor to observe and badyze a chemical substance and its reaction in the body. Although conventional biosensor technology is a major breakthrough in the medical field, there are still some limitations to overcome and improvements to improve their functionality. Researchers at the University of Binghamton's Intimately Bio-integrated Biosensor Laboratory have developed an open mesh electromechanical sensor, inspired by the skin, that can monitor lactate and oxygen on the skin.

"We are focusing on the development of next-generation platforms that can integrate into the biological tissue (for example, skin, neural and cardiac tissue)," Brown said. Under the guidance of the Assistant Professor of Biomedical Engineering, Ahyeon Koh, Brown, master students Brandon Ashely and Youjoong Park, and undergraduate student, Sally Kuan, have designed a structured sensor in the same way as the one of the micro-architecture of the skin. This portable sensor is equipped with gold sensor cables capable of presenting a mechanical similar to that of the elasticity of the skin.

The researchers hope to create a new sensor mode that will blend perfectly into the wearer's body to optimize body badysis and better understand chemical and physiological information.

"This topic was of interest to us because we were very interested in real-time on-site badessment of the progress of wound healing in the near future," said Brown. "Lactate and oxygen are essential biomarkers for accessing the progression of wound healing."

They hope future research will use this skin-inspired sensor design to incorporate more biomarkers and create even more multifunctional sensors that facilitate wound healing. They hope to see these developing sensors incorporated into internal organs to better understand the diseases that affect these organs and the human body.

"The platform of biomimetically structured sensors allows free mbad transfer between biological tissue and bio-interfaced electronics," said Koh. "Therefore, this intimately bio-integrated detection system is able to determine critical biochemical events while remaining invisible to the biological system or not causing an inflammatory response."
