MICRO & BIO-MIMETIC MODELING AND DESIGN / DEVELOPMENT OF MICRO-BIO SYSTEMS FOR MICAV


Development of Chemical and Biosensors at NDRF


A focus area for NDRF and its consortium partners is chemical and biosensors to detect toxic gases and pathogens. This has been supported by the National Program for Micro Air Vehicles (NPMICAV). A biosensor to detect nitric oxide using its natural receptor Guanylyl cyclase with luminescence intensity as the indicator was taken to proof of concept to prototype stage by of NDRF and a device fabricated by bigtec. A simulation model was also developed by NDRF based on experimental data from the nitric oxide biosensor.

A miniaturized biological collection payload and micro PCR for detection of bacterial (anthrax) pathogen is being developed by bigtec. A Lab on Chip prototype to sense ammonia was developed by Anna University in collaboration with Concordia University of Canada. Jain University is developing a nano biosensor for detecting ammonia, for using in a micro air vehicle. Jain University is also working on R&D for a biofuel cell.


Development of Simulation Model for Biosensors


Project on “Micro and Bio-mimetic Modelling and Design / Development of Micro-Bio system for MICAV (Biosensor for Detection of Nitric Oxide using its Natural ligand Guanylyl Cyclase)” has been sanctioned by AR&DB. The Project is directly handled by NDRF with Dr. L. V. Muralikrishna Reddy, as the Principal Investigator. The first phase of the project is being carried out in collaboration with IISc, Abexome Pvt. Ltd and bigtec Pvt. Ltd. The progress achieved till date and the critical experimental results obtained at the NDRF / bigtec / IISc are very encouraging and have yielded deliverables. A detailed presentation has been made to the Programme Review Committee of NP-MICAV at National Aerospace Laboratories.

The Objective of the Project is to build a simulation model of nitric oxide biosensor, using enzyme kinetics. The simulation will be done using Bioinformatics software COPASI, Genesis and MATLAB.


TO STUDY EFFECTS OF MORPHING WINGS ON MICAVS



NDRF has been sanctioned a NP-MICAV Project to study Effect of Morphing Wing on Micro Air Vehicles MICAVs). Morphing the wings as in natural filers has several advantages. The purpose of this project is to evaluate the cost and benefits of the three different designs-elbow joint on wing rotation, for enhanced lift. The main aim of the project is to develop a 300 mm Flapper Wing MAV with elbow joints based using a small spring. The elbow is allowed to bend during upstroke and straightness during down/power stroke. A flapping wing MICAV with elbow joints “frozen” was used. A pin was inserted through the elbow joint to prevent bending at the joint. This MAV has an all-up weight of 17.5 gms, endurance of 14.2 minutes and runs on a 130mAHr 3.7 V LiPo battery. Flight tests have proved that the lateral stability gets affected with the elbow joint. Springs of different stiffness were tried out to confirm stability issues different CG locations were tested with no change in the stability issue. However, although straight line flight is relatively stable, but even the slightest change in heading would lead to a compromise in stability. This particular design needs further studies to understand the cause of instability to enable us to take advantage of the benefits of low velocity lift offered by these arrangements in the absence of any literature on this subject.


DESIGN AND DEVELOPMENT OF A TRANSITIONING VTOL MICAV



NDRF is developing a Transitioning VTOL (Vertical Takeoff and Landing) under a NP-MICAV project. VTOL platforms have several advantages, the most important being their ability to take off and land from confined spaces and the ability to hover and stay stationary at any position. VTOL platforms in hover are very stable platforms for various sensors, including imaging and chemical detection.

This 300mm micro transitioning vehicle is a flying wing planform and utilizes a bi-rotor configuration in hover mode. Either elevons, or independent motor tilt will be utilized for control during hover. In hover mode, the bi-rotors will utilize contra rotating propellers and have independent speed controls using high update rate controllers.

To enter the fixed wing mode, the motors will tilt forward until the MICAV transitions completely. Control during high alpha, for fast hover, will also be possible.

This project has completed the first year where in MINIAV was develop and the and Second year of the Project involves developing of 300 mm Micro VTOL.

DESIGN AND DEVELOPMENT OF 125MM FLAPPING WING MAV



Micro Air Vehicles (MICAV) are being used for surveillance in disaster management, search/rescue and security applications Fixed wing MICAVs are utilized for longer ranges and where higher speeds are acceptable.


Flapping wing MICAV or Ornithopter attempt to imitate wing kinematics and utilize the flapping wings for lift and thrust. Because of their near invisible structure (Rods, and transparent covering for the most part of it) they will have the ability to get close to the object of interest un-noticed. Their physical appearance also aids in stealth operation

Flappers are much more power efficient than rotary wings. Flappers also have the ability to hover, and sometimes even fly backwards making them very maneuverable platforms. Flappers can also fly past windows, doors and through corridors to help collect more data from the area of interest.

NDRF has successfully developed a 125mm span Flapping Wing MICAV under a NP-MICAV Project that has the potential for surveillance application and disaster management. The Project was reviewed in January 2015 by the Review Committee of NP-MICAV

BIOSIMULATION

NDRF was sanctioned to build a simulation model of nitric oxide biosensor, using enzyme kinetics. The model is a cumulation of enzyme kinetic behaviour of the each enzyme in the biosensor. It was concluded that experimental variation exists within a system that needs to be taken into consideration which makes it unsuitable for integration into the sensor. This project is successfully closed.



DEVELOPMENT OF PROTOTYPE AND MANUFACTURE OF NON-INVASIVE GLUCOMETER USING NIR SPECTROMETRY



NDRF has taken up a project jointly with Indian Council of Medical Research (ICMR) to develop a Glucometer for Non-Invasive Measurement of Blood Glucose in Diabetic Patients by using (Near Infra-Red-NIR) NIR- emitter and silicon photo detector with wave length of 100 to 1100nm. The instrument measures the absorbance of NIR in the blood and displays the readings on the display as ADC (analogue to digital values) which is computed to the blood glucose levels in Mg/dl. and displayed on the instrument or computer screen using proprietary software application. The advantages of using this glucometer are that, it needs no piercing of the Skin, no blood samples are taken and hence doesn’t cause any pain to patients. As it does away with needles or chemical strips there is no cost involved to buy them. Once the Meter is purchased, the only cost that is involved is in purchasing the battery, which is a consumable. One diabetic patients who have to undergo repeated tests of their blood glucose level will certainly find cost reduction in their expenses, using this unit.
Indian Council of Medical Research (ICMR) funded Project “Development and Manufacture of Non-Invasive Glucometer” handled by NDRF in collaboration with Indus Biomedical Devices has been progressed well. The first Prototype was successfully validated and clinical trials conducted at Jnana Sanjeevini Medical Centre & Diabetes Hospital Bangalore. It is expected that the final Non Invasive Glucometer can be delivered with the calibration, and validation within the stipulated project deadline. To finalize this into a product suitable modification in software and algorithm are under progress. The functioning of the Prototype Glucometer successfully demonstrated recently at ICMR and the Authorities at ICMR were satisfied with the development of the Product.
