Design of a MEMS Bolometer with Absorptive Element as Piezo-Protein

H. Sinha [1], A. Mukherjee[1], N. Chattoraj[1],
[1]Birla Institute of Technology Mesra, Ranchi, Jharkhand, India

Bolometer is a thermal infrared sensor used for measuring the intensity of radiation via the heating of a material due to the radiations. A bolometer consists of an absorptive element, a thin layered material, connected to a thermal reservoir. The result is that any radiation received on ... En savoir plus

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 ... En savoir plus

Alternative Designs to Harness Natural Convection in Flow Batteries

A. Ansari [1], S. Kumar [1],
[1] Department of Chemical Engineering, Indian Institute of Science, Bangalore, Karnataka, India

The earlier work in our group has established that natural convection plays a dominant role in SLRFB. We used it to run a battery in which interestingly, the contents are agitated for brief spells when no current flows through it. The present work focuses on electrode configurations ...
