“…In recent years, sensors printed on polymer substrates represent an increasing area of research and development due to the growing demand for biosensors [1], artificial skin [2], chemical sensors [3], force [4] and strain sensors [5][6][7][8][9]. In particular, resistive strain sensors on polymeric substrates are employed, in general, for the measurement of forces [6], movements [7] and displacements [8].…”

a b s t r a c tRecently, inkjet printing technology has received growing attention as a method to produce low-cost large-area electronics, sensors, and antennas on polymer substrates. This technology relies on printing techniques to deposit electrically functional materials onto polymer substrates to fabricate electronic components or sensing elements. In this paper, we applied an inkjet printed technology for the development and characterization of films on a polymer substrate aiming at giving design considerations for the optimization of strain sensors or printed electronics obtained by inkjet printing. Two inks were tested over a polyimide substrate, a water-based conductive polymer, PEDOT:PSS, and a silver nanoparticles ink. Their sensing capabilities were investigated under tensile conditions and various strain histories (strain ramp; cyclic loading-unloading tests; application of constant strain over prolonged time) aiming at highlighting the correlation between electrical response, applied strain, time and mechanical histories. Furthermore, the mechanical viscoelastic response of the substrate was investigated under similar strain histories interpreting the results at the light of the substrate deformational characteristics and evaluating its influence.

“…[43] These features are very attractive for e-skin in robotics, where fast, reliable and repeatable response is much desired. [2] Other graphene-based solutions, which can also be used in robotic systems, are flexible and transparent strain sensors, [83] flexible supercapacitors [84] and gas sensors on bendable and soft substrates. [85,86] In that sense, current focus of the graphene research is the fabrication of large area graphene electrodes on flexible substrates for touch sensor and smart window applications.…”

New materials and advances in making electronic skin for interactive robots

Flexible electronics has huge potential to bring revolution in robotics and prosthetics as well as to bring about the next big evolution in electronics industry. In robotics and related applications, it is expected to revolutionise the way with which machines interact with humans, real-world objects and the environment. For example, the conformable electronic or tactile skin on robot's body, enabled by advances in flexible electronics, will allow safe robotic interaction during physical contact of robot with various objects. Developing a conformable, bendable and stretchable electronic system requires distributing electronics over large non-planar surfaces and movable components. The current research focus in this direction is marked by the use of novel materials or by the smart engineering of the traditional materials to develop new sensors, electronics on substrates that can be wrapped around curved surfaces. Attempts are being made to achieve flexibility/stretchability in e-skin while retaining a reliable operation. This review provides insight into various materials that have been used in the development of flexible electronics primarily for e-skin applications.

“…(1)(2)(3)(4) Graphene-based flexible devices are attracting increasing attention owing to their excellent stretchability and flexibility, and graphene's ability to tolerate severe strain of up to 30%, (5) making it a leading candidate for flexible devices. However, research on applications of graphene for flexible devices has been limited by constraints in producing large-scale graphene films on flexible substrates, namely, high synthesis temperatures, difficulty maintaining consistent quality between samples, fabrication cost, and difficulties associated with particular synthesis techniques.…”

A flexible laser-reduced graphene oxide (LRGO) strain gauge formed on a polyethylene terephthalate (PET) substrate is fabricated using a new technique suitable for large-scale and low-cost mass production. The LRGO film is initially synthesized by drop-casting a graphene oxide (GO) solution on a flexible PET substrate, followed by the simultaneous reduction and patterning of the dried film with a 1.8 W carbon dioxide laser. The LRGO film is then characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, and scanning electron microscopy (SEM). A multilayer LRGO film with an estimated average thickness of 2.5 µm and good adhesion to the PET substrate is obtained. The measured gauge factor of the LRGO strain gauge is 61.5.
