not well-suited with the planar geometry of most electronic devices. Hence, planar interdigitated microscale charge storage devices are gaining importance over conventional fl ip-chip devices. [1][2][3] Fabrication of such microscale electronic devices is a major challenge because the methods used have to be facile, effi cient, and compatible with those used in the other fl exible device fabrication protocols. Various techniques such as lithography, physical vapor deposition using shadow mask, sputtering, laser writing, etc., have been used to fabricate planar interdigitated microsupercapacitors till date. [4][5][6] Except the laser-based methods most other methods are somewhat complicated or time consuming. Of course, they do have specifi c advantages of concurrent wafer scale processing and scalability that cannot be underplayed. Laser-based device fabrication methods are however mostly single step, simple, and fast. Most of these have used laser power for the synthesis or direct writing of conducting carbon. [7][8][9] In this paper, we report an even simpler and faster method of device fabrication using fast CO 2 laser scribing of a layer of mushroom-synthesized conducting carbon to fabricate a planar microsupercapacitor on a fl exible substrate. This approach can be easily extended to other presynthesized forms of carbon for electrochemical doublelayer capacitors (EDLCs) or metal oxides/sulfi des for pseudocapacitors. We also point out that the mushroom-synthesized carbon in our case is formed by using a specifi c hydrothermal preprocessing protocol not used before and naturally renders few layer graphene-graphitic composite that offers the concurrent advantage of fl exibility and high conductivity. Mushroom has been used earlier as a precursor for carbon synthesis [ 10,11 ] but in these works precarbonization at low temperature of 500 °C was employed instead of hydrothermal preprocessing (used in the present work) before activation.Flexible planar microsupercapacitors have some serious issues like low energy density and low stability that limit its practical application. To improve the device performance, the quality of the electrode plays a signifi cant role. It has been reported that mesoporous carbon-based electrodes in EDLCs show great promise for microsupercapacitors both in terms of stability and energy density. [ 12 ] This type of material also offers A report is presented on the fabrication of all solid-state interdigitated fl exible microsupercapacitor using ultrafast and highly scalable laser scribing technique, using highly mesoporous carbon synthesized from biomass (mushroom) with hydrothermal preprocessing. The specifi c protocol used for carbon synthesis renders some unique property features to the material (surface area of 2604 m² g −1 with hierarchical pore size distribution) in the context of supercapacitor electrode application. A polyvinyl alcohol (PVA)-H 2 SO 4 gel electrolyte is used for electrochemical measurements. The microsupercapacitor shows high cyclic stability up to 15000 cycles....

“…Laser induced carbonization from polymer lms was rst demonstrated for the fabrication of high-performance carbon MSCs by using high-power CO 2 infrared pulse lasers and 522 nm pulse lasers. [45][46][47][48][49] Recently, we demonstrated the fabrication of highperformance all-solid-state exible carbon MSCs by laser direct writing on polyimide (PI) lms in air using a relatively low-power compact continuous-wave blue-violet semiconductor laser with a wavelength of 405 nm, the power of which can almost be totally absorbed by the PI lm. 50 We further conducted the similar laser direct writing process on PI lm with only changing the air to inert atmosphere with argon (Ar) gas, resulting in highly increased conductivity, specic surface area, and pore size distribution, thus greatly improved energy and power densities.…”

A high-performance all-solid-state flexible interdigitated carbon/TiO 2 micro-supercapacitor (MSC) with photo-rechargeable capability was prepared by combining a laser direct writing technique with electrophoretic deposition of TiO 2 nanoparticles. The carbon/TiO 2 MSC shows the same excellent capacitive performance as the pure carbon MSC, such as high specific capacitance up to 27.3 mF cm À2 at a typical current density of 0.05 mA cm À2, excellent cycling stability, long-time stability, and mechanical stability. Under UV light irradiation, the carbon/TiO 2 MSC can be charged to above 100 mV, and still maintain 60 mV after 10 photo-charging cycles, demonstrating its photo-rechargeable capability. What's more, after 10 photo-charging cycles, the carbon/TiO 2 MSC shows no capacitive performance degradation, which can be attributed to the high structural stability of the carbon/TiO 2 MSC under UV light irradiation.

“…Further analysis of the irradiated areas using transmission electron microscopy revealed that the laser process liberated carbon monolayers from the PI substrate, creating a porous graphene network on the sample surface. This discovery led to the now widespread use of laser-induced graphene for developing DLW capacitors [20][21][22] and sensors [23].…”

Direct laser write process for 3D conductive carbon circuits in polyimide

Direct laser writing (DLW) is a versatile materials processing technique often applied to device prototyping. However, a fast and cost effective DLW process for fabricating three-dimensional (3D) conductor-insulator composites has yet to be demonstrated. In this work, polyimide (PI) is established as a viable platform for creating 3D graphitic circuits through ultrafast DLW. Under optimized processing conditions, graphitic material with a resistivity of 6 Ω·cm was formed in the laser irradiated regions. A thermal and microstructural material model is proposed for the non-linear DLW process and its graphitic products. The process is demonstrated to be an inexpensive and rapid technique for creating electrical contacts to nanoscale components. Future applications of the technique range from nanowire power generation to 3D integrated photonic and electronic devices.0a The
