“…Similarly, the use of integrated sensors for the defense to diffuse arsenal after sensing its remote presence is another important area. Thus, the flexibility of chemical modification in macromolecule to design multi-functionality for wide range sensing and control the atmospheric as well as to enrich other significant branches of science and engineering like robotics [ 125 , 126 ]. Some other proposed focus area for integrated sensors is controlled delivery in agriculture and biomedical, précised controlled and action in robotics, demining in controlled of terrorism and security for futuristic efforts in sensing sciences.…”

Impact of macro molecular theory on the progress of sensing sciences and technology has been presented in the light of materials developments, advances in physical and chemical properties. The chronological advances in the properties of macromolecules have significantly improved the sensing performances towards gases, heavy metals, biomolecules, hydrocarbon, and energetic compounds in terms of unexplored sensing parameters, durability, and working lifetime. In this review article, efforts have been made to correlate the advances in structure and interactivity of macro-molecules with their sensing behavior and working performances. The significant findings on the macromolecules towards advancing the sensing sciences are highlighted with the suitable illustration and schemes to establish it as a potential “microanalytical technique” along with existing challenges.

“…In the present study, ionic polymer–metal composite (IPMC), one of the most optimal and novel biological classes of the EAPs [ 15 , 16 , 17 , 18 , 19 , 20 ], was used as an artificial muscle (a soft-active actuator) with two different mechanisms to restore eyelid movement following ptosis. IPMCs have higher repeatability and more biocompatibility with lower required voltage as compared to other EAP classes for working in a wet biological condition [ 21 , 22 ].…”

Enhanced Ionic Polymer–Metal Composites with Nanocomposite Electrodes for Restoring Eyelid Movement of Patients with Ptosis

The present study aims to use enhanced ionic polymer–metal composites (IPMC) as an artificial muscle (a soft-active actuator) to restore eyelid movement of patients with ptosis. The previous eyelid movement mechanisms contained drawbacks, specifically in the lower eyelid. We used finite element analysis (FEA) to find the optimal mechanism among two different models (A and B). In addition to common electrodes of IPMC (gold and platinum), the bovine serum albumin (BSA) and microcrystalline cellulose (MCC) polymers, with optimal weight percentages of carbon nanotube (CNT) nanofiller, were also utilized as non-metallic electrodes to improve the efficiency of the IPMC actuator. In both models, IPMC with nanocomposite electrodes had higher efficiency as compared to the metallic electrodes. In model A, which moved eyelids indirectly, IPMC with MCC-CNT electrode generated a higher force (25.4%) and less stress (5.9 times) as compared to IPMC with BSA-CNT electrode. However, the use of model A (even with IPMCs) with nanocomposite electrodes can have limitations such as possible malposition issues in the eyelids (especially lower). IPMC with MCC-CNT nanocomposite electrode under model B, which moved eyelids directly, was the most efficient option to restore eyelid movement. It led to higher displacements and lower mechanical stress damage as compared to the BSA-CNT. This finding may provide surgeons with valuable data to open a window in the treatment of patients with ptosis.

“…[6][7][8][9] A well-known example of ion-exchange membranes are ionic polymer-metal composites (IPMCs), which typically consist of a cation-exchange membrane chemically plated with a noble metal, such as gold or platinum. [7,10,11] Following the application of an electric voltage between the surface electrodes, IPMCs display macroscopic bending deformations. [12] Vice versa, a mechanical load applied to an IPMC results in a measurable voltage across its electrodes.…”
