AmorePacific Embraces “High Tech” Beauty With Touch Sensor and UV/Biometric Monitors


>>> EVENT ALERT: During Beauty Acceleration 2022, experts from The Estée Lauder Cos., BeautyStat, GOOP and Belcorp will explore how technology is advancing consumer engagement and R&D innovation. Join us on September 28-29, 2022 in New York. Register now for the best rates.

Emerging from its CES Innovation Awards in 2021 and 2022, AmorePacific has taken “high tech” beauty this year with collaborations to develop a sensor to measure skin touch, an approach to dynamically visualize UV ​​dose and more recently , and a wireless electronic skin to monitor biometrics and UV exposure. These advances could benefit the development of skin care and beauty products.

Chipless and wireless biometric monitoring

Recently, AmorePacific funded the work of a cohort of researchers, primarily from the Massachusetts Institute of Technology (MIT), who developed chipless electronic skin capable of detecting biological signals related to pulse, sweat, and exposure. to UV. The book was published in Science.

Wearable sensors are ubiquitous thanks to wireless technology, and can transmit glucose levels, blood pressure, heart rate, activity, and more, according to a report from MIT. from person to smartphones for analysis. These sensors run off conventional chips and power sources, but next-gen iterations take on smaller, thinner, and more flexible forms, like the one featured here.

At the heart of the new sensor design is an “ultra-thin film of high-quality gallium nitride”, which has piezoelectric properties: it can produce electrical signals in response to mechanical stress or vibrate in response to pulses. electrical. The researchers showed that it could vibrate in response to a person’s heartbeat or the salt in their sweat, and could be read by a nearby receptor, suggesting it could monitor biological signals.

“If there’s a change in the pulse, or chemicals in the sweat, or even UV exposure to the skin, all of that activity can change the surface acoustic wave pattern on the gallium nitride film.” , notes Yeongin Kim, lead researcher on the MIT study. “And the sensitivity of our film is so high that it can detect these changes.”

Skin sensation sensor

In related work, in January 2022, AmorePacific announced the development of the “world’s first touch sensor” to measure skin sensation. The research, published in the journal ACS Nano, describes “flexible pyroresist graphene composites” for artificially differentiating between materials and solvent types using thermosensation.

As the company explains, the smart sensor takes measurements and uses machine learning to recognize the levels of coolness and moisture felt by human skin, as well as types of solvents. It converts measurements into numerical values, and this information can support the development of cosmetic products with optimal touch characteristics. The work was carried out in collaboration with the Ulsan National Institute of Science and Technology (UNIST).

Park Young-ho, Technical Director of AmorePacific’s R&I Center, said, “The sensor can accurately compare and measure the level of coolness or warmth provided by cosmetic products and, therefore, provide objective results.”

Dynamic UV dose, visualized

Finally, as previously reported, researchers from AmorePacific and Hanyang University in Seoul have developed an approach to dynamically visualize UV ​​dose to sun-protected skin. They reported that UV dose is determined by several external factors, including sunscreen properties, weather, type of outdoor activity, etc., and therefore devised a framework to dynamically visualize UV ​​dose. ‘UV depending on these factors.

A 3D model of human skin was created using triangular mesh, which was positioned in static postures to mimic outdoor activities. The angle of the sun relative to points on the “skin” was then tracked from the time-dependent properties of sunscreen and color-mapped using software to indicate states before 1 MED was reached . This work has been published in Skin research and technology.
