Artificial skin sweats on command

Phys.org  July 27, 2022 Following their previous work on artificial sweating skin an international team of researchers (the Netherlands, Italy) demonstrated three-dimensionally steered dynamic liquid mobility at nanoporous liquid crystal polymer coatings. The release of fluid is stimulated by UV light. Upon a primary flood exposure to UV light, liquid is ejected globally over the entire coating surfaces. They reallocated the secreted liquid by applying a secondary electric field stimulus. By doing so, the liquid is transported and collected at pre-set positions as determined by the electrode positions. They monitored the process in real-time. Through precise analysis they found that […]

Integrating microchips for electronic skin

Science Daily  January 22, 2020 To closely replicate natural skin, it is necessary to interconnect a large number of individual sensors. An international team of researchers (Japan, Germany) developed a sensor system that consists of a 2 x 4 array of magnetic sensors, an organic bootstrap shift register, required for controlling the sensor matrix, and organic signal amplifiers. All electronic components are based on organic thin-film transistors and are integrated within a single platform. The researchers demonstrated that the system has a high magnetic sensitivity and can acquire the two-dimensional magnetic field distribution in real time and very robust against […]
