A joint research team at CNU developed a wearable bioelectrode that can be attached to a human body to read various bio-signals and an encryption technology for anti-counterfeiting.

Professor Park Jong-jin of the CNU School of Polymer Science and Engineering has developed a wearable healthcare sensor that can measure one’s emotional status as well as heart rate, joint movement, and breathing through joint research with Deers-I Co., Ltd. (CEO: Kwon Joo-yeol) and Tara Distribution Co., Ltd. (CEO: Lee Jae-soo).

This is also an anti-counterfeiting encryption technology that adjusts the pore size of the carbon electrode and can read hidden information through the path of light, of which the size of the fine pores is adjusted when light is reflected on the information in the background.

The results of this study were published online in the Journal of Materials Chemistry A (Impact Factor: 11.301) on March 9.

In particular, the research team said that the carbon electrodes used in wearable healthcare and anti-counterfeiting optical tags have good breathability and are human-friendly without causing skin irritation or environmental harm as they are biodegradable in soil within 14 hours.
