An important aspect in this regard is the effective fluidic communication between the reservoir and the MNs on a robust substrate. In a novel attempt of its kind, we present the development hollow SU-8 MNs on a pre-etched silicon wafer having through holes. SU-8 MNs are fabricated by direct laser writing by aligning them on the silicon substrate with microfluidic ports pre-etched by wet chemical etching. Each process step was optimized after a parametric study.
The MNs have been characterized for mechanical strength and biological insertion tests for their effectiveness in puncturing the skin without breaking. The maximum compressive force and bending forces for the MNs are 0. The microfluidic characterizations show the development of hollow MN lumen with a flowrate of around 0.
Further, the SU-8 polymer films can be turned into a fracture-resistant, glassy form of carbon that holds immense promise for drug delivery.
Heat treatments in an oxygen-free oven sharpened the microstructures into microneedles composed almost exclusively of randomly ordered carbon atoms.
Characterizations revealed the glassy carbon structure could exert forces strong enough to pierce human skin with minimal risk of breakage.
They promise novel manufacturing techniques such as printed electronics, roll-to-roll fabrication; applications such as wearable electronics for health diagnostics; flexible sensors and actuator arrays such as displays and image sensors etc.
However, these advantages are followed by a host of reliability issues in devices and interconnect. Interconnects on flex experience open circuit fault during operation due to mechanical flexing, differential thermal expansion, electro static discharge, electro migration and environmental degradation.
To improve the reliability of the interconnect to open failures several passive approaches such as stretchable conductive materials, meandered and helical geometries, the use of spongy substrates etc have been investigated. These approaches however are passive and only improve the reliability of the interconnect to mechanical causes of failures.
We describe an active approach where in open faults in interconnects are automatically detected and repaired in real time during operation. The self healing mechanism is achieved using a dispersion of conductive particles in an insulating fluid that is packaged over the interconnect. Upon the occurrence of a fault in a current carrying interconnect, the field developed across the gap polarizes the particles in the dispersion.
The polarized particles then experience dipole-dipole attractive forces and form a bridge across the gap thereby healing the fault. In this talk, we present the physics and results pertaining to the stability of the heal, the time taken to heal and the stretchability of the heal. He is also the founder and director of openwater. Such a breakthrough could enable amazing new capabilities and products — from rollable displays combining the functions of TVs and computing, to stretchable wearable products and ultra-thin mobile devices.
Applied Materials is at the forefront of providing OLED display and flexible roll-to-roll R2R manufacturing solutions that can help enable technology innovations for creating new generations of more lightweight, flexible form factor products. In this talk, Dr Suraj Rengarajan will focus on process technologies that are critical to moving flexible displays from a vision to a reality. The presentation covers R2R processing inflections for the display and IoT industries and explores how creating flexible form factors for next-generation consumer electronic devices requires the use of polymeric films.

Most of these polymeric materials are manufactured in the form of a roll, resulting in the increased utilization of R2R processing. He will also discuss how Applied is developing R2R technologies for next-generation, large-area flexible electronics applications.
Current active areas of research include: Cosmology and large scale structure, Galactic and extragalactic astronomy, Classical and quantum gravity, Cosmic magnetic fields, Gravitational waves, High energy astrophysics, Instrumentation for astronomy, Interstellar medium, Optical astronomy, Radio astronomy, Solar Physics. TIFR has a well-established department of Astronomy where cutting edge research in theoretical and observational astrophysics including instrumentation is carried out.
The research interests of the department can be broadly categorized into three groups: The observations are carried out using ground based facilities as well as balloon-borne and satellite-borne instruments. NCRA, the radio astronomy facility set up by TIFR at Pune, has an active research program in many areas of Astronomy and Astrophysics, which includes studies of the Sun, interplanetary scintillations, pulsars, the Interstellar medium, active galaxies and cosmology.
It is an open access facility and is used by astronomers across the world. This has resulted in some unique contributions like optical observations of the afterglow of gamma-ray burst, a few micro-lensing events and quasar variability, new ring systems around Saturn, Uranus, and Neptune were also discovered.
The Institute hosts two telescopes of apertures 1 and 1. The satellite is designed for the study of cosmic sources simultaneously over a wide range of the electromagnetic spectrum; from optical bands to high energy X-rays.

This simultaneous multi-wavelength capability will allow ASTROSAT to make very important contributions in many areas of Astronomy, particularly in the simultaneous multi-wavelength monitoring of intensity variations in a broad range of cosmic sources, the X-ray sky for new transients, sky surveys in the hard X-ray and UV bands, studies of periodic and non-periodic variability of X-ray sources, broadband spectroscopic studies of X-ray binaries, AGN, SNRs, clusters of galaxies and stellar coronae.
Though Indian astronomers have been using some of the existing m class international facilities, only three 2 m class optical-IR telescopes exist in India to be supplemented by a 3. Motivated by the limited access to the high end observing facilities and the near impossibility of building a large optical observational facility of its own, India has ventured into the TMT project as a key player.
Being partners rather than guest observers in the TMT project with a resolution 12 times better than the Hubble Space Telescope, Indian astronomical community will enjoy a level playing field with leading international astronomers besides mastering technology to build large facilities of their own.
Among the three gravitational-wave detectors presently located in USA, the plan is to move one of these detectors to India where site survey has been already carried out. The strategic importance of the third LIGO detector being set up in India is that it offers the longest baseline possible on earth.
A consortium of several institutes in India have come under a single banner called IndIGO Indian Initiative in Gravitational-wave Observations to evolve a strategy towards turning the Indian gravitational-wave initiative into reality.
The science benefits of this experiment are enormous given the multi-disciplinary nature of the experiment. It will attract and benefit scientists and engineers from fields like optics, lasers, gravitational physics, astronomy and astrophysics, cosmology, computational science, mathematics and various branches of engineering.
The next major upcoming facility is the India-based neutrino observatory INO. It is an underground facility to study fundamental issues in science especially neutrino oscillations. Further, the success of Chandrayaan-1 mission that found evidence of water molecules on the moon, perfect launch of the Mars orbiter spacecraft making it the first Indian made object to leave the Earth's sphere of influence and other major initiatives like these have opened up a host of opportunities for space exploration using indigenous technology.
