“…PPy exhibits low solubility in common organic solvents, so through electrochemical synthesis, it is possible to produce composite actuators. Besides, interfacial polymerisation allows the production of highly conductive materials [130]. Encapsulated PPy is developed using gel (polymethyl methacrylate PMMA) as the electrolyte and doped with salt [131].…”

Mechanical actuators are defined as mechanical devices that convert an input energy into motion. Since the 1990s, advancements in the fields of robotics and automation have produced a critical need for the development of lightweight and efficient actuators capable of human-like motion. In the past few decades, extensive research activities in the fields of materials science and smart materials have led to the development of a novel type of actuator known as artificial muscles. This review paper describes the evolution of mechanical actuators from conventional technologies such as electric, hydraulic, and pneumatic actuators, to bioinspired artificial muscles. The working mechanism, manufacturing process, performance, and applications of different artificial muscles are described and compared with those of conventional actuators. Details on the cost, input sources, activation modes, advantages, and drawbacks of each artificial muscle technology are also provided to guide the reader through the intricate selection process of the bestsuited actuator for a specific application.

“…Figures 2 a and b show the results of the DSC analysis of the conductive fillers and paste vehicle without the filler, respectively. The DSC curve of PPy/TiO 2 NC filler shows a slight shift of PPy melting temperature (55 °C) towards higher temperatures (61 °C) on account of the improved crystallinity of PPy in the presence of TiO 2 nanoparticles [ 57 ]. The outcome results indicated the melting point T m of the paste vehicle, which was equal to 78 °C.…”

“…Characteristic peaks at 916 and 1,044 cm −1 are related to CH out of‐plane vibration and CH in‐plane vibration, respectively (Cordeiro et al, 2015). The peak at 1,182 cm −1 , assigned to pyrrole ring vibration and 1,548 cm −1 band is corresponded to C═C and CC stretching bends (Santos & Oliveira, 2014). The band at 3435 cm −1 , assigned to NH stretching band of the pyrrole ring.…”

In this study, polypyrrole nanoparticles were synthesized by chemical methods on polyester elastic substrates. SEM images represent the uniform distribution of polypyrrole nanoparticles. Using polypyrrole modified fiber, the analysis system was designed and used as a portable texture analyzer to measure the mechanical properties of food samples. In the designed system, there was a linear and significant relationship between the changes of applied force and the electrical resistance of the elastic fiber. In this device, changes in the applied force can be obtained by tracking changes in electrical resistance. After obtaining a linear relationship between the force and electrical resistance changes for each fiber, the optimal sensor was selected by high sensitivity, the lower detection limit, and higher R2. Subsequently, for the validation of designed device, the biodegradable films based on different materials were used. The results obtained from the designed device and the texture analyzer showed that the designed device has high accuracy and error rate of less than 10%, which indicates the matching of the data obtained from the texture analyzer and the designed device. These results suggest the ability to use a designed device instead of the texture analyzer device to analysis mechanical properties of food samples. Practical application The designed device is very cheap and easy to work with. The device is easily capable of measuring mechanical properties such as stress–strain curves, fracture force, and tensile strength in food products and biodegradable polymers. Due to its portability, this device is capable of on‐site analysis and reduces the cost of material analysis to a great extent.
