Piezoelectric Ultrasonic motors (USM) are based on the principle of converse piezoelectric effect i.e., vibrations occur when an electrical field is applied to piezoelectric materials. USMs have been studied several decades for their advantages over traditional electromagnetic motors. Despite having many advantages, they have several challenges too. Recently many researchers have started focusing on Industry 4.0 or Fourth Industrial revolution phase of the industry which mostly emphasis on digitization & interconnection of the entities throughout the life cycle of the product in an industrial network to get the best possible output. Industry 4.0 utilizes various advanced tools for carrying out the nexus between the entities & bringing up them on digital platform. The studies of the role of USMs in Industry 4.0 scenario has never been done till now & this article fills that gap by analyzing the piezoelectric ultrasonic motors in depth & breadth in the background of Industry 4.0. This article delivers the novel working principle, illustrates examples for effective utilization of USMs, so that it can buttress the growth of Industry 4.0 Era & on the other hand it also analyses the key Industry 4.0 enabling technologies to improve the performance of the USMs.

“…Using several electrical actuation systems is a way to change the trailing edge of airfoil. This method can increase the aerodynamic efficiency from aspects of higher lift/drag ratio and better pitching moment control 7 . Dependency to electrical motors such as servo motor have own limitations and lack of flexibility and also electric motor need extra mechanisms to change rotational forces to axial forces considering high electrical power consumption with low efficiency 4 , 5 , 8 .…”

In this research, by inspiration of natural myosin motion in artificial muscle contraction, a new method for changing the thickness of an airfoil has been proposed by hybrid of mixed integration electrolysis module and chemical reaction (HEFR) of sodium bicarbonate (NaHCO3 (s)) and acetic acid (CH3COOH (l)). The mentioned method has the ability to create pressure in the fluid in a short time and fast transfer without delay due to the integration of the method in the fluid transfer tube to soft sealed skin. With soft sealed skin swelling and movement of solid skeletal structure, the force is transmitted to the desired mechanism. First, for a single of soft skin and solid structure, remarkable displacement over time in the various loading condition (by the inflation tester) has been investigated. It is shown that the proposed mechanism is capable of moving 246 g during 3 s with total mechanism weight of 10 g. In the following, the mechanism is developed into a symmetrical rhombus (set of soft skin-solid structure) with the ability to contract and expand to provide variable airfoil thickness. The proposed mechanism has the ability to move in the horizontal and vertical axis (expansion and contraction) in lower than 5 s by applying the HEFR technique. Such a mechanism is mounted on a symmetrical airfoil and has the ability to change the airfoil thickness with the appropriate response time. The proposed mechanism can be used in various industrial applications such as robotics.

In this research, an artificial muscle filament (AMF) as a novel mechanism and small part of the artificial muscle is proposed in which, considering the real natural mechanism and necessity and constructability of industrial manufacturing engineering, AMF with no electric power supply for expansion/contraction provides the conspicuous strong and fast displacement. AMF, inspired by nature, based on the sliding filament theory and combination of advantages of soft and hard materials, employs artificial actin (AA, scissor mechanism) and artificial myosin (AM, soft material). Volume change of AM for displacement of AA is resulted from proposed chemical reaction of sodium bicarbonate (NaHCO3 (s)) solution with water (l) and acetic acid (CH3COOH (l)) which the main advantages of high power to weight ratio (more than 10 times), mimicking nature and expandable to artificial muscle are obtained in simple module structure. Response speed of AMF can be adjusted by controlling the flow rate and gas output from less than 1 second to desired amount. In this study, by applicable notice on numerical simulation of particle dynamics and experimental tests of AM, a laboratory model of AMF with displacement of 50 mm has been fabricated which for various ranges of flow rate and loading condition is evaluated. The AMF based on the filament theory close to nature, due to overcoming the limitation of conventional artificial muscle and correspondingly advantages of simplicity in fabrication and modularity, low cost and weight, high power and fast response time, the proposed mechanism may be employed especial place for the some future industrial applications.
