Ionic polymer-metal composites (IPMC) are typical electromechanical transducing materials suitable for use as soft actuators, bioinspired artificial muscles and sensors. However, IPMC produced with platinum films has the great disadvantage of large number cracks wrinkles, which reduce performance electrode. Polyaniline (PANI) is a promising conductive polymer that can address this issue, especi...

Urban areas with trees provide several ecosystem services to citizens. There is a growing interest in for the removal of air pollutants such as particulate matter. The objective this paper show study on variation intercepted matter concentration (IPMC) by tree leaves megacity Bogotá (Colombia). relationship between IPMC and PM2.5 concentrations observed quality stations two urban zones differen...

The cownose ray (Rhinoptera bonasus) demonstrates excellent swimming capabilities; generating highly efficient thrust via flapping of dorsally flattened pectoral fins. In this paper, we present a bio-inspired and free swimming robot that mimics the swimming behavior of the cownose ray. The robot has two artificial pectoral fins to generate thrust through a twisted flapping motion. Each artifici...

An ionic polymer-metal composite (IPMC) actuator composed of a thin perfluorinated ionomer membrane with electrodes plated on both surfaces undergoes a large bending motion when a low electric field is applied across its thickness. Such actuators are soft, lightweight, and able to operate in solutions and thus show promise with regard to a wide range of applications, including MEMS sensors, art...

BACKGROUND Noninvasive intraductal papillary mucinous neoplasms (IPMNs) have a favorable prognosis; however, the prognosis of invasive intraductal papillary mucinous carcinoma (invasive IPMC) is poor. Identification of predictive factors for differentiating IPMC from benign IPMNs would assist in providing appropriate treatment. DESIGN Retrospective study (1999-2006). SETTING Wakayama Medica...

An inverted pendulum fitted on the moving cart (IPMC) represents a class of nonlinear system and is inherently unstable. Stabilizing such nonlinear systems is still a challenging objective for control engineers. It is very difficult to keep the pendulum always in upright position as it is highly sensitive to even a small disturbance and tend to fall down. Hence, the objective of the control mec...

The medical, rehabilitation and bio-mimetic technology demands human actuated devices which can support in the daily life activities such as functional assistance or functional substitution of human organs. These devices can be used in the form of prosthetic, skeletal and artificial muscles devices (Andreasen et al., 2005; Bitzer & Smagt, 2006; DoNascimento et al., 2008). However, we still have...

Ionic polymer–metal composites (IPMCs) are soft actuation materials with promising applications in robotics and biomedical devices. However, traditional IPMC actuators can generate the bending motion only. In this paper, a lithography-based approach is presented for monolithic, batch-fabrication of IPMC actuators that are capable of complex deformation. Such an actuator consists of multiple, in...

BACKGROUND AND AIMS Intraductal papillary mucinous tumours (IPMT) of the pancreas constitute a unique pathological entity with an overall incidence of associated invasive malignancy of 20%. The malignant potential of an individual IPMT cannot be accurately predicted. Preoperative estimation of the risk of associated invasive malignancy with IPMT would be of significant clinical benefit. As aber...

Ionic polymer–metal composite (IPMC) is a promising candidate for underwater sensing due to the merits of rapid response, flexibility, miniaturization, and self-powered nature.
