56 FLEX007 MAGAZINE I APRIL 2019 continuing growth. It seems like you're on a good path here. Kannurpatti: We believe so. We are driving in that direction and receiving positive responses from our customers too. This is an exciting time for us. Goldman: Regarding this expansion, is it going to be all new products? Kannurpatti: We plan to make new as well as existing products in the assets. Goldman: Are you developing for semi-additive and additive processes? Kannurpatti: Absolutely. Our customers use those processes, so we support them. Part of the power of bringing both the heritage DuPont and Dow sides of our portfolio is being able to support that. Not only do we supply the dielectric materials and the photoresist materi- als—such as Kapton®, Pyralux®, and Riston®, which come from the heritage DuPont side— but we also have all of the plating and pro- cessing chemistries for metallization from the Dow side. When you think about semi-additive or modified semi-additive processes, having expertise and products that come from both sides helps deliver an integrated solution for customers. Thank you for giving us the opportunity to talk to you. We are looking forward to con- tinuing to share where we stand on things and would be more than happy to have more con- versations when there is news to share. Goldman: Yes, it sounds like there will be more news in June. Thank you for your time. Johnson: Thanks for giving us an overview. This has been very informative for me. Kannurpatti: Thank you. FLEX007 Researchers at Binghamton University's Intimately Bio- Integrated Biosensors lab have developed skin-inspired, open-mesh electromechanical sensor that is capable of monitoring lactate and oxygen on the skin, allowing for long-term, high-performance, real-time wound monitor- ing in users. "We are focused on developing next-generation plat- forms that can integrate with biological tissue," said Matthew Brown, a Ph.D. student at Binghamton University. Under the guidance of Assistant Professor of Biomedical Engineering Ahyeon Koh, Brown, master's students Bran- don Ashely and Youjoong Park, and undergraduate stu- dent Sally Kuan designed a sensor that is structured simi- larly to that of the skin's micro architecture. This wearable sensor is equipped with gold sensor cables capable of exhibiting similar mechanics to that of skin elasticity. The researchers hope to create a new mode of sen- sor that will meld seamlessly with the wearer's body to maximize body analysis to help understand chemical and physiological information. Hopefully, future research will utilize this skin-inspired sensor design to incorporate more biomarkers and create even more multifunctional sensors to help with wound healing. The sensors could be incorporated into internal organs to gain an increased understanding about the dis- eases that affect these organs and the human body. "The bio-mimicry structured sensor platform allows free mass transfer between biological tissue and bio-interfaced electronics," said Koh. "This intimately bio-integrated sensing system is capable of determining critical biochemical events while being invisible to the biological sys- tem or not evoking an inflammatory response."
