“…Selective ablation provides a powerful tool for high-resolution (sub-micron scale) subtractive patterning of graphenebased layers in a rapid and versatile way [178][179][180][181][182][183][184]. Graphene-based films, even with micrometric thicknesses, can be laser-patterned for the fabrication of electrode structures that can be used in a wide variety of apparatus, such as microheaters, thermal sensors, and thermostatic devices [185]. For obtaining accurate ablation, with minimal impact on the substrate or any underlying layers, femtosecond laser patterning has proved to be more appropriate than processing using longer laser pulses.…”

This paper describes a novel, multilayered hot embossing method for fabricating a microstructure pattern on various polymer substrates. The method involves a multilayered hot embossing process with three polymer substrates (polycarbonate, polymethyl methacrylate, and low-density polyethylene), three pieces of microstructured molds, and graphene-based heaters. Only one hot embossing step is required in which a microstructure pattern is directly fabricated onto the three polymer substrates. The total processing cycle time is less than that of the traditional hot embossing process. In this study, thin graphene-based heaters were fabricated and tested. A facility that integrates graphene-based heating and multilayered hot embossing was designed and implemented. Under the proper processing conditions, a hemispherical microlens array and a microcylinder array pattern were successfully fabricated on the three polymer substrates. Finally, the uniformity of embossing temperature and the replication quality of the microstructure patterns were measured and analyzed. The technique shows great potential for the rapid and flexible fabrication of microstructure patterns on various polymer substrates.

“…Among them, the graphene material has high thermal conductivity, and the thermal conductivity coefficient is very high. It can quickly conduct heat from one area to another, and it can quickly and evenly distribute the heat during the heating process, so it is a very ideal material for being used in the manufacture of heaters. − However, the process of preparing these materials through the traditional way is complicated with high cost and a long preparation period. In this article, laser-induced graphene (LIG) was prepared on PI films by the laser direct writing technique, , and the prepared LIG exhibited high porosity, excellent electrical and thermoelectric properties, and good mechanical flexibility. ,, At the same time, the preparation is simple, and the preparation cost is low − (Table S1).…”

This paper proposes an LIG-based flexible sensing and heating system for food monitoring (FTMS) for frost protection of food in cold storage. The FTMS integrates two major components: flexible temperature sensing and a flexible laser-induced graphene (LIG) heating patch. Factors affecting the performance of flexible LIG heating patches were investigated from the electrical, thermoelectric, and microscopic levels of the flexible LIG heating patches. The best performance of the prepared flexible LIG heating patches was achieved when the power was 12.5% and the scanning rate was 120 mm/s. In the simulation application phase, through this system, an antifrostbite test is carried out on oranges, pears, and other fruits; when the output voltage is about 3 V, it only takes 14−20 s from the time the fruit meets the cold damage to the time the temperature is pulled back to the set range, and the results show that this system could effectively resist frostbite and monitor the surface temperature of the fruits efficiently. It has a high application value in reducing food waste rates. In the future, we could look forward to its application in rare plant protection and high-value-added crop protection.
