Ms. Sushmita Wills(lecturer) who is doing her PhD on nano-sensors has agreed to help us with the project. Ms. Wills is currently working on glucose level detection in the interstitial fluid using current flow variations in the transistors. Right now all the data and research papers available are being gathered and the work on this area will also start in full flow soon.

About the bio sensor that is a crucial part in this project......we
know that it is possible...and that similar sensors exists in the
market presently.....but we are having a tough time getting hold of
one.Since our current focus is on the electronics part....we will be
happy to have a rough idea about the signal from the sensor.I mailed
one Dr.Martin M. F. Choi, PhD9,Associate Professor
Department of Chemistry, Hong Kong Baptist University) and here is
what he mailed me back.....:

------------------------------------------
For amperometric glucose biosensor, a dissolved oxygen electrode was
used to capture the change in dissolved oxygen after the enzymatic
reaction. A dissolved oxygen is a Clark-type electrode comprising a Pt
electrode and a Ag electrode. The applied voltage to the electrodes is
about 0.6 V. The current generated is about in mA level (I don't know
exactly the values).

For optical glucose biosensor, the optical signal (at about 610 nm)
was captured by a photomultiplier tube (PMT). Normally, the applied
voltage to the PMT is 1000 V. However, I don't know exactly the
current generated from the optical signal because the PMT used was
from a spectrofluorometer.
-------------------------------------------------

I guess the first one to be more appropriate data for our purposes.I
suppose we could start with a 0.5V to 1.0V, 2mA to 5mA , and a very
low frequency (something like 10hz) signal.

It's beautiful.....wow!!!!....it might be pretty unprofessional to write down my feelings in a K-log but i like a personal touch to my work....it was love at first sight for an electronics engineer....to hold in hands not one but a whole quadrant of PSoCs....each with increasing capabilities and wow! so cute.....!!!!..I forgot all about the exams that i had the next day.....but i had to wait.................
....the next day I installed the required software.....PSoC Express, programmer and other paraphernalia.I hooked up the mini-programmer to the 3209 and toggled the "device power" and the whole thing came to life....cap-sense,LED and all.It was like a teaser to one of those movies ...one that u can't wait to see.i worked out the first demo, the decaying LED one....the Express made the whole thing look so easy.....i tried a few variations...using priority encoder and setPointRegion.Express did the whole work for me...made it look very easy but i need to dig deeper....find out how it is exactly done....try to achieve it with Designer to get a deeper idea of how to make it work...but presently i plan to complete all seven demos in Express itself.And i need to find out how to give an external analog/digital input to CY3209.(.....just to remind myself at a later date.....how to hook it to another kit...in cascade..if required) .I have collected related application notes from cypress .....many of them were thankfully available in our Direct Client Share....we are simultaneously trying to get a clearer idea of the bio-sensor....prakash has already located some useful ones....we have located two juniors who is working on Glucose sensors for their bio project lab....
..among other news...it was anounced in our "Analog Electronics" class that all 10 of our lab experiments would be carried out on PSoC as part of the curriculum.....It is definitely a first in many aspects for sure!...and we count ourselves very lucky.
.....so long then.....

I am Savio Joseph 3rd year BE Hons Computer Science and i am the head of Finance and Logistics department for the NOVOSPES team.
Our hopes are pretty high thanks to the encouragement from engineers, VC's, Judges and people all around us. Right now myself and Rajath will be working on creating a prototype of the Website and we are evaluating various platforms and technologies for the same. Joomla, a CMS based on PHP and My-SQL, merits our attention, but we are evaluating other technologies also.


With regard to the financial part, we have decided to contribute our prize money from the Epsilon B-plan competition as our initial capital investment.

Novo Spes aims at providing every one of the 40 million diabetics a personal diabetes monitoring and management solution. The product called Glucawatch comprises of a wrist worn continuous glucose monitoring device and an online diabetes support and consultancy program .The wrist device will provide the user with a high/low indication of the user's glucose level thus keeping a continuous watch. It will alert the user whenever the glucose level crosses the thresholds.

A tiny glucose‐sensing biosensor will be inserted just under the skin of user's abdomen. The insertion will be quick and painless. The sensor continuously monitors the interstitial fluid glucose and outputs the data to the wrist worn display device wirelessly.

Combined with the Glucawatch is a service called Dr. Gluca which intends at giving the users a complete medical support wherein they will find themselves monitored by the best in the business. The users will just have to maintain a log on their medical profile on the net or via telephone which will enable our team of doctors to provide them with medical advice in the comfort of their homes. The doctor will be in a position to prescribe insulin dosage, required tests and anything else that may be needed. This means minimal visits to the diabetologist in town, saving both money and time. Not only this, the online support forum will give the users an opportunity to interact and get in touch with other diabetics, thus providing them not only advice from their peers but also a sense of belonging to a community.

Right now in India continuous glucose monitoring systems are still a thing of the future. Besides any such device available abroad costs a fortune because of the way the technology is being implemented in them. A point to be noted here is that knowing the specific blood glucose value at all times is not necessary for a diabetic but what's more important is keeping it in the safe zone. The devices that are available right now measure the exact blood glucose levels whereas Glucawatch uses polling and compares the results with the limits of the safe zone continuously. Thus Glucawatch serves the purpose without complicating the technology allowing us to have technologically simpler sensor resulting in much lower cost of production. As far as Dr.Gluca is concerned it is the first of its kind dedicated exclusively to diabetics in the market right now.

India has the second largest number of diabetics second only to china, of which 10% are type I. The distribution between rural and urban areas is 75:25.The annual expenditure of a family on one diabetic per year ranges from 22% on an average varying from 59% in the low socioeconomic group, 32% in the middle socioeconomic group, 18% in the upper middle income group and 12% in the high‐income group. Glucawatch fits in very well in the socioeconomic picture of the diabetics in India. The fact that it is cheaper than any such product abroad along with it being a unique product in Indian market makes it a perfect choice.

Right now an Indian customer uses a blood glucometer, which is an invasive device and the cost of using it comes to around Rs.5k + Rs.500/month. In contrast a glucawatch user will be able to monitor his/her glucose levels for about Rs.15k(expected) + Rs.250/month not to mention the fact that it will monitor the glucose levels 24X7. The product will be subject to approval by the Central Drug Standard Control Organization (CDSCO) and this may take some time due to the rapid research in this bio sensor field. The product will have to go through intense research and testing, to eliminate any discrepancies in the glucose levels shown

Hey guys this is suyog. Im the group leader for this small group of ours, we call NovoSpes. Yesterday we got a mail from cypress saying that our project was mentioned by the MD of cypress semiconductors to the CEO during their quarterly operations presentation at san joes head-office. well all of us are really excited after this and we are feeling really honoured by this. I personally consider this as an achievement after getting the 2nd spot in EPSILON-a national level b-plan competition.
good job guys keep it up.
