Predicting Effective Elastic Properties of Nanocomposites Using COMSOL Multiphysics® Software

K. Das [1], N. Mishra [1],
[1] Indian Institute of Technology Bhubaneswar, Bhubaneswar, Odisha, India.

In this work the effective elastic properties of a SU8 photoresist matrix reinforced with ZnO nanomaterial (in the form of cylindrical nanowires, spherical and ellipsoidal particles) have been evaluated employing COMSOL Multiphysics® software. The Solid Mechanics physics interface of ... Read More

Design and Simulation of Electroactive Polymer-Based Artificial Muscles for Biomedical Application

A. S. Tripathi [1], B. P. Chatterjee [2], S. Das [3],
[1] Advanced Technology Development Centre, Indian Institute of Technology Kharagpur, Kharagpur, India
[2] Dept. of Cardiology, Medical College and Hospital, Kolkata, India
[3] School of Medical Science and Technology, Indian Institute of Technology Kharagpur, Kharagpur, India

Electro-active polymer (EAP) based actuators are one of the suitable contenders for use in artificial muscles based bio-medical application because of their bio compatibility and lower active actuation voltage requirement phenomenon. At present Ionic polymer metal composites (IPMC), a ... Read More

Experimental Investigations and Numerical Simulation of Electrothermally Actuated Micro-gripper

B. K. S. Kishor[1], T. Ramesh [1],
[1] NIT Trichy, Tiruchirappalli Tamil Nadu, India.

At the micron-level, thermal actuation exerts larger forces compared to the widely-used electrostatic actuation. To obtain large displacements at low voltage the principle of Electro Thermal actuation is used. It works on the principle of selective non-uniform Joule heating which results ... Read More

Optimization of Device Geometry of a Fully-Implantable Hearing Aid Microphone

A. Dwivedi [1], G. Khanna [1],
[1] National Institute of Technology Hamirpur, Himachal Pradesh, India

The hearing impairment is affecting more than 360 million people all over the world.In India alone, 63 million people suffer from the significant auditory loss. Conventional hearing aids suffer from reliability, practicality and social stigma concerns. The totally implantable devices ... Read More
