This paper presents numerical simulation of plate wave modes in thin stainless steel plates using a racetrack spiral coil electromagnetic acoustic transducer (EMAT), which works under the principle of acousto-elastic effect, called Lorentz force mechanism. EMATs are useful for non ... Read More

Simulation of the Electrode-Tissue Interface with Biphasic Pulse Train for Epi-retinal Prosthesis

S. Biswas[1], S. Das[2], M. Mahadevappa[2]
[1]Advanced Technology Development Center, Indian Institute of Technology, Kharagpur
[2]School of Medical Science and Technology, Indian Institute of Technology, Kharagpur

Retinitis Pigmentosa (RP) and Age-related Macular Degeneration (AMD) are diseases causing blindness in a large number of people. In this type of degenerative disease, mostly the photoreceptors are damaged. Thus attempts have been made to electrically stimulate the surviving inner retinal ... Read More

Piezotyres

T. Madhuranath[1], R. Praharsha[1], K. Srinivasa Rao[1]
[1]Lakireddy Bali Reddy College of Engineering, Mylavaram, Andhra Pradesh, India

Access to electricity has become a major problem. In the process of solving this problem we should consider even a small source of electricity. Piezotyres are made to produce electricity from vehicle tyres. For this we have used a piezoelectric property, one of the natural wonder. COMSOL ... Read More

Modeling and Simulation of Drug Release Through Polymer Hydrogels

V. Runkana[1], S. Maheshwari[1], S. Cherlo[1], RSR Thavva[1]
[1]Tata Research Development and Design Centre, Tata Consultancy Services Ltd., Pune, Maharashtra, India

Polymer hydrogels are commonly used as carriers or vehicles for the controlled release of drugs, primarily because of their bio-compatibility and because rates of drug release can be controlled by manipulating polymer properties like molecular weight, cross linking ratio, etc. Drugs can ...
