Low-cost sanitary napkin disposal machine

Aiswarya Paramadathil from AdiShankara Institute of Engineering and Technology, Kerala developed a Low-cost sanitary napkin disposal machine.

The issue of sanitary waste is a major problem. So, a technology is developed for the disposal of sanitary napkins using lowcost chemicals. The napkin-dissolving solution collects in a septic tank and thereby does not pave way for any kind of pollution. The device works under the principle that cotton gets dissolved in a chemical named Cuprammonium Hydroxide [Cu(NH3)4(OH)2] and its non-woven part can be recycled and used for making bags and covers. The cottondissolving chemical solution is passed to the septic tank while the undissolved nonwoven cotton is collected in a waste tray. The used napkin is put through the inlet of the machine, where it is shred to pieces by the AC single-phase induction motor. The shred napkin pieces go to the reaction chamber, where the reaction between the napkin and Cu(NH3)4(OH)2 takes place.low-cost-sanitary-napkin-disposal-machine The required amount of both chemicals needed for destroying one napkin is delivered into the reaction chamber through a tube, controlled by a solenoid valve. The approximate amount of the final chemical required to destroy one napkin is about 150 ml. 150 ml of dissolving solution contains 87 ml NH4OH and 8 gm of Cu(OH)2. Thus, the sanitary napkins are completely destroyed. The innovator has filed a patent for his work on internet for low-cost sanitary napkin disposal machine.

For this innovation a low-cost sanitary napkin disposal machine she received appreciation award in Gandhian Young Technology Innovation Award 2016 organized by SRISTI at Rashtrapati Bhawan, New Delhi

mSleep: Measure your sleep

Shuchita Gupta & Yashovardhan Sharma from Indraprastha Institute of Information Technology, Delhi developed a mSleep: Measure your sleep with the help of their guide Dr Vinayak Naik.

The amount of sleep affects an individual’s health. The gold standard of measuring sleep and diagnosing sleep disorders like sleep apnoea is polysomnography which, though accurate, is expensive and lacks portability. A number of wearable devices with embedded sensors have emerged in the recent past as an alternative for regular sleep monitoring directly by the user. These devices, however, are intrusive and cause discomfort besides being expensive. msleepThis work presents an algorithm to detect sleep by using a smartphone, with the help of its inbuilt accelerometer sensor. The device consists of airflow (for rate of respiration), pulse oximeter (for heart rate and oxygen saturation), accelerometer (PLM) and EEG (brain waves) sensors.

The data is stored on cloud; results are summarised and seen on phone by the doctors and patients. The accuracy of sleep detection was compared with that of Zeo sensor, based on electroencephalogram (EEG) sensor to detect sleep. In order to concisely represent the sleep quality of people, the sleep data was modeled using Hidden Markov Model (HMM). The innovation allows people to easily and seamlessly measure their sleep, without requiring a lot of technical know-how, while helping to diagnose a very commonly occurring disease (>10% of the population), sleep apnoea. This also aids the doctors in tracking and studying the sleeping habits of patients remotely.

For this innovation mSleep: Measure your sleep, they received appreciation award in Gandhian Young Technology Innovation Award 2016 organized by SRISTI at Rashtrapati Bhawan, New Delhi

Straut AERO: Solar industrial hot-air generator

Sharad Parekh from University college of engineering & Technology, Ahmedabad developed a Straut AERO: Solar industrial hot-air generator with the help of his guide Dr Nilesh Bhatt.

The hot air is a preferred choice of the industry as a source of process heat fluid when compared with other sources like thermal fluid or water. The industries currently use natural gas, coal or biomass as a fuel to heat air. A typical small industry consumes about 20-30 one million British Thermal Units (MMBTU) per day for hot air. However, the increasing cost of fossil fuels and emissions are a continuous concern.


The consumption of coal and natural gas for heating of air leads to carbon emissions. More efficient or greener sources of process heat/hot air is required to avoid these carbon emissions. To address this problem, the innovator developed a product called STRAUT Aero.

It uses solar energy to generate hot air which is ready to be deployed for industrial purposes. The prototype of solar air heater generator uses a heat collector. It consists of three major elements: heat collection element, reflector and header. Heat collection element receives the reflected energy available from the reflector. Reflector increases the aperture area and reflects the energy on the heat collection element while the header is used to provide for inflow and outflow of the energy. In AERO, this heat collection element is having a special design that makes it very efficient with air as a fluid. The reflector is also used to increase the aperture area. The concentration ratio of reflector and receiver depends on the temperature and mass flow rate. The successful working prototype is already operational. The maximum temperature of 300 deg.C can be achieved by this solution, which covers all major process air heat application of industries.

For this innovation called Straut AERO: Solar industrial hot-air generator, He received appreciation award in Gandhian Young Technology Innovation Award 2016 organized by SRISTI at Rashtrapati Bhawan, New Delhi

E-Droid Meter

Bitu C Ghoniya from Sarvajanik College of Engineering & Technology, Gujrat with the help of her team Shruti B Patel, Jigisha M Karangiya, Jinal N Modi and Guide Urmi Desai she developed an E-Droid Meter. e-droid-2

Problems with electricity bill have always been there, for example one cannot ensure that how accurate his/her bill is, one cannot predict the bill and cannot find out how much one pays per unit. So, a project which can help in solving these problems is built. The consumption of individual appliances is analysed. A device is made which will continuously measure consumption of every appliances and these data e-droid-1will be transferred to the server so that one can check and see the usage of appliances graphically. The biggest advantage of this system is that one can turn on/off the power of appliances remotely. One can get notifications when any appliance exceeds its threshold value and that particular appliance will be turned off automatically. The device can be used in residential and commercial areas, for analysing power consumption of appliances and to save energy.

For this innovation called E-Droid Meter, they received appreciation award in Gandhian Young Technology Innovation Award 2016 organized by SRISTI at Rashtrapati Bhawan, New Delhi


Cost-effective mechanical testing equipment for characterising creep behaviour of materials under combined tension-torsion loading

A young engineering student from Indian Institute of Technology, Kharagpur Vineesh K P developed a Cost-effective mechanical testing equipment for characterising creep behaviour of materials under combined tension-torsion loading with the help of his guide Prof. Vikranth Racherla.

1Components in several engineering applications like gas turbines, nuclear power plants, boilers etc., experience stress at relatively high temperatures, causing them to undergo time-dependent permanent deformation (referred to as creep deformation). It is important to characterise the creep behaviour of materials for various loading and temperature histories, to be able to predict shape changes and component life in such applications. The team has designed, fabricated and tested a mechanical-cum-creep testing machine that can measure elongation and twist, with high resolution in samples, subjected to tension and torsion loadings at given temperatures. The fabricated prototype of our machine is different from other commercially available ones in the following regard: (i) Ability to apply combined tension-torsion loads, (ii) Measurement of creep behaviour under time-varying temperature/loads, (iii) High measurement resolution (length changes of the order of 100 nm), (iv) Horizontal machine layout, simplifying reconfiguration, maintenance and assembly, (v) Lower cost, and (vi) Modular nature of machine, allowing easy reconfigurability. 

Martensitic stainless steel ss410 is used for all parts except for linear guide way, rail blocks, ball screw, and bearings which are purchased directly. ss410 offers a unique combination of corrosion resistance, excellent strength on heat treatment and magnetic property (which is useful e.g. for holding work pieces on magnetic chucks during grinding operations on parts) at a price that is considerably less than the austenitic grade stainless steel such as ss304. while in annealed condition, at which it is procured and machined, it has an yield strength of around 275 mpa its yield strength increases to around 1000 mpa by heating it to temperatures of 925-1010°c, oil quenching it, and finally tempering it at 200°c for around 2 hours.

For this Cost-effective mechanical testing equipment, they received appreciation award in Gandhian Young Technology Innovation Award 2016 organized by SRISTI at Rashtrapati Bhawan, New Delhi
