As a new intelligent material, IPMC (Ionic polymer-metal composite) can be driven under low voltage with large deformation, and has been widely used in biomedical and robotic systems. Traditional IPMC testing system is bulky, high cost, and inconvenient to use. In order to achieve the portability and convenience of the IPMC testing system, a small and low-cost IPMC tester was designed. The power supply and control system of the tester were integrated into an IPMC electrode clamp. The main research work included control system circuit design, electrode clamp and overall exterior design. The displacement measurement results showed that the design for the IPMC tester was correct and feasible.

Biomimetic is the field of engineering in which biological creatures and their functions are investigated and are used as the basis for the design and manufacturing of machines. Ionic Polymer Metal Composite (IPMC) is a smart material which has demonstrated a meaningful bending and tip force after the application of a low voltage. It is light-weighted, flexible, easily actuated, multi-directional applicable and requires simple manufacturing. Resultantly, IPMC has attracted scientists and researchers to analyze it further and consider it for any industrial and biomimetic applications. Presently, the research on IPMC is bi-directional oriented. A few groups of researchers are busy to find out the causes for the weaknesses of the material and to find out any remedy for them. The second class of scientists is exploring new areas of applications where IPMC material can be used. Although, the application zone of IPMC is ranging from micropumps diaphragms to surgical holding devices, this paper provides an overview of the IPMC application in biomimetic and biomedical field.

Irrigation systems are becoming increasingly important, owing to the increase in human population, global warming, and food demand. This study aims to design a low-cost autonomous sensor interface to automate the monitoring and control of irrigation systems in remote locations, and to optimize water use for irrigation farming. An internet of things-based irrigation monitoring and control system, employing sensors and actuators, is designed to facilitate the autonomous supply of adequate water from a reservoir to domestic crops in a smart irrigation systems. System development lifecycle and waterfall model design methodologies have been employed in the development paradigm. The Proteus 8.5 design suite, Arduino integrated design environment, and embedded C programming language are commonly used to develop and implement a real working prototype. A pumping mechanism has been used to supply the water required by the soil. The prototype provides power supply, sensing, monitoring and control, and internet connectivity capabilities. Experimental and simulation results demonstrate the flexibility and practical applicability of the proposed system, and are of paramount importance, not only to farmers, but also for the expansion of economic activity. Furthermore, this system reduces the high level of supervision required to supply irrigation water, enabling remote monitoring and control.

This paper discusses a low cost solution to teaching controls in the laboratory through the use of a novel balance beam. The balance beam provides a vehicle to study many aspects of both control implementation and control algorithms. Due to the complexity of the system, a full semester of laboratory exercises is provided for even advanced students. The flexibility of the system provides challenging exercises for different levels of education. A low overall cost translates to accessibility to more schools. The ability to achieve good tracking performance with a simple cascaded loop controller makes this an ideal tool for teaching controls in a laboratory setting.

This paper describes the development of a tube-shaped ionic polymer-metal composite (IPMC) actuator with sectored electrodes and an integrated resistive strain-based displacement sensor. Tube or cylindrical shaped IPMC actuators, with the ability to provide multiple degrees-of-freedom motion, can be used to create active catheter biomedical devices and novel bio-inspired propulsion mechanisms for underwater autonomous systems. An experimental tube-shaped IPMC actuator is manufactured from a 40-mm long Nafion polymer tube with inner diameter of 1.3 mm and outer diameter of 1.6 mm. The outer surface of the tube-shaped structure is plated with platinum metal via an electroless plating process. The platinum electrode on the tube’s outer surface is sectored into four isolated electrodes using a simple surface milling technique. A custom-designed strain sensor comprised of 50 AWG ni-chrome wire is developed and attached to the tube’s surface to sense the bending motion of the tube actuator. The integrated sensor is low cost and practical, and it avoids the need for bulky external sensors such as lasers for measuring deflection and feedback control. Preliminary experimental results are presented to demonstrate the performance of the IPMC tube actuator and integrated displacement sensor.
