CEPHALOPOD-INSPIRED DYNAMIC THERMOREGULATORY MATERIALS

Systems to control the thermal performance of the many entrenched technologies are ubiquitous in electronics, clothing, food packaging, buildings, and their environment control platforms. These thermal management systems are classified as “passive” or “active” depending on the mode of operation, and the passive thermal management in particular is relatively inexpensive, energy efficient, and easy to install. Despite these advantages, a typical passive thermal management system is difficult to control by users, therefore, development of an ideal thermal management system that merges the advantages of passive systems with dynamic control functions of active systems is required. In this research sub-section, we developed a static infrared-reflecting composite material, inspired by squid skin, with mechanically tunable thermoregulatory properties, and verified that this material has outstanding figures of merit, in terms of tandem infrared reflectance and transmittance modulation, excellent stability to repeated mechanical cyclability, straightforward manufacturability, and possesses a compatible working mechanism. We aim to further apply our materials to the various fields of packaging, clothing, and electronics industry, ranging from traditional ones, such as clinical warming devices and shipping containers, to emerging ones, such as conformable electronic skin and untethered soft robots.
