Epidermal electronic systems (EESs) are skin-like electronic systems, which can be used to measure several physiological parameters from the skin. This paper presents materials and a simple, straightforward fabrication process for skin-conformable inkjet-printed temperature sensors. Epidermal temperature sensors are already presented in some studies, but they are mainly fabricated using traditional photolithography processes. These traditional fabrication routes have several processing steps and they create a substantial amount of material waste. Hence utilizing printing processes, the EES may become attractive for disposable systems by decreasing the manufacturing costs and reducing the wasted materials. In this study, the sensors are fabricated with inkjet-printed graphene/PEDOT:PSS ink and the printing is done on top of a skin-conformable polyurethane plaster (adhesive bandage). Sensor characterization was conducted both in inert and ambient atmosphere and the graphene/PEDOT:PSS temperature sensors (thermistors) were able reach higher than 0.06% per degree Celsius sensitivity in an optimal environment exhibiting negative temperature dependence.

“…Screen printing metallization is the most widely used contact formation technique for commercial Si solar cells . Ag flake is the most mature technology and remains the most widely utilized technique currently used in the manufacturing of conductive elements . However, these flakes or particles do not allow high‐resolution printing with the linewidth smaller than 70 µm, which results in high shadow losses .…”

PE has been explored for the manufacturing of flexible and stretchable electronic devices by printing functional inks containing soluble or dispersed materials, [14][15][16] which has enabled a wide variety of applications, such as transparent conductive films (TCFs), flexible energy harvesting and storage, thin film transistors (TFTs), electroluminescent devices, and wearable sensors. [17][18][19][20][21][22][23][24] The global PE market should reach $26.6 billion by 2022 from $14.0 billion in 2017 at a compound annual growth rate of 13.6%. [25] PE devices are manufactured by a variety of printing technologies. Typical printing technologies can be divided into two broad categories: noncontact patterning (or nozzle-based patterning) and contact-based patterning. The noncontact techniques include inkjet printing, electrohydrodynamic (EHD) printing, aerosol jet printing, and slot die coating, while screen printing, gravure printing, and flexographic printing are examples of the contact techniques. Each of these techniques has its own advantages and disadvantages, but they all rely on the principle of transferring inks to a substrate. Understanding the characteristics and recent advances of each printing technique is important to further the progress in PE. Moreover, to promote the lab-scale printing technologies to large-scale production process, roll-toroll (R2R) printing, which is one of the manufacturing methods to obtain large-area films with low cost and excellent durability, has drawn much attention from both industry and the research community.Nearly all of devices based on PE require conductive structures, interconnects, and contacts; therefore, highly conductive patterns, usually with high transparency and/or high resolution, fabricated by means of printing conductive materials are one of the most critical components in PE devices. Various printable conductive nanomaterials, such as metal nanomaterials (e.g., metal nanoparticles and metal nanowires) and carbon nanomaterials (e.g., graphene and carbon nanotubes (CNTs)), have been explored and used as major materials for PE. Applying printing technology to deposition of the conductive nanomaterials requires formulation of suitable inks. After depositing inks on different substrates, post-printing treatment, Printed electronics is attracting a great deal of attention in both research and commercialization as it enables fabrication of large-scale, low-cost electronic devices on a variety of substrates. Printed electronics plays a critical role infacilitating widespread flexible electronics and more recently stretchable electronics. Conductive nanomaterials, such as metal nanoparticles and nanowires, carbon nanotubes, and graphene, are promising building blocks for printed electronics. Nanomaterial-based printing technologies, formulation of printable inks, post-printing treatment, and integration of functional devices have progressed substantially in the recent years. This review summarizes basic principles and recent development of common printing technologie...

“…Wearable sensors for e‐skins are generally prepared by assembling patterned active materials onto or encapsulated in elastomers . To achieve this, a series of processing techniques have been developed, such as infilling, lithography, screen‐ or inject‐printing, and 3D printing . Although great achievements have been made by these methods, they are suggested to have the following drawbacks including complex procedures, cost ineffectiveness, or poor scalability .…”

Electronic skins (e-skins) have been widely investigated as important platforms for healthcare monitoring, human/machine interfaces, and soft robots. However, mask-free formation of patterned active materials on elastomer substrates without involving high-cost and complicate processes is still a grand challenge in developing e-skins. Here, SiC-based strain sensor arrays are fabricated on elastomer for e-skins by a laser direct writing (LDW) technique, which is mask-free, highly efficient, and scalable. The direct synthesis of active material on elastomer is ascribed to the LDW-induced conversion of siloxanes to SiC. The SiC-based devices own a highest sensitivity of ≈2.47 × 10 5 achieved at a laser power of 0.8 W and a scanning velocity of 1.25 mm s −1 . Moreover, the LDW-developed device provides a minimum strain detection limit of 0.05%, a small temperature drift, and a high mechanical durability for over 10 000 cycles. When it is mounted onto human skins, the SiC-based device is able to monitor external stimuli and human health conditions, with the capability of wireless data transmission. Its potential application in e-skins is further proved by an LDW-fabricated device having 3 × 3 SiC sensor array for tactile sensing.
