OBJECTIVE
My objective is to invest 10 million dollars which I won last Friday in a lottery and I need to invest
this money in any field of MEMS.
From the past few decades, the MEMS devices are gaining popularity in every field like from
Defense, Fluids, Medical, and Computers to Space. To select one product for investment is
difficult but I would like to invest in Medical field. The component in which I would like to invest
will be BioMEMS Sensor Systems for Bacterial Infection Detection.
DESCRIPTION
MEMS product are available in every sector and the main reason behind the popularity of MEMS
is small size. In medical field, many BioMEMS devices are present like sensors for pressure,
temperature, DNA factors, Glucose, chemical ion, oxygen and Carbon dioxide level checking, and
Action devices like Microfluidic Pumps, Fluid filters, DNA amplification/analysis and more
devises are present. [1]
BioMEMS SENSORS Systems for Bacteria detection are the sensors which detect harmful
bacteria. As harmful bacteria is present on everything which we use in our daily life like on food,
clothes and on many more things. Some bacteria have natural resistant to some antibacterial but
some bacteria is of that kind whose solution till now is not present, but in both cases detection of
presence of bacteria is needed and for this purpose BioMEMS sensors for bacteria detection are
used. The best way to stay away from drug resistant Bacteria is to find out their colonies, identify
their type, monitor them and finally destroy them before they come in contact with human body.
[2]
For detection of bacteria, highly sensitive MEMS resonant sensors in which a combination of
surface acoustic waves circulating over the top of piezoelectric substrate have been projected for
the detection of bacteria and their colonies. This technology helps in the development of low cost
and highly efficient detection method to detect, identify and monitor the drug resistant bacteria
with of the order of 1 picogram. The advantage of such type of sensors is that it can also monitor
the progression of a specific bacterial colony growing in real time in houses, public places and
many more which is very helpful in saving the many lives [2].
LITERATURE REVIEW
Research work is going on MEMS in every field. But the very first MEMS devices used in
biomedical industry were blood pressure sensors in the 1980s. After lots of innovations in pressor
sensors came like to monitor glaucoma, the MEMS implantable pressure sensors are used to check
fluctuation in intraocular pressure (IOP) which is main risk factor for glaucoma [3].
Many more BioMEMS Devices were developed for BioMEMS based DNA sequencer was
developed by Cepheid in 2003 [4]. BioMEMS drug delivery systems like Micro pumps for drug
delivery, Micro-fabricated microneedles etc. were developed which are still going well. [5]
Also, Surgical Microsystems, Diagnostic Microsystems and Therapeutic Microsystems were
developed which are allowing intelligent, precision surgery with a shorter recovery time for the
patient. [6]
Biotech product like Bodymedia Bedbug, SenseWear WMS, and SenseWear BMS – Wearable
sensors, TELTONIC ikcal- Biofeedback device for health monitoring and behavior modification
are present [7].
Lots of research is going on in the field of MEMS has ran to the explosion of micro devices in
medical field, in future lot of new BioMEMS will come to save the life of human beings.
CONCLUSION
I can conclude that my reasons behind the investment in BioMEMS are the first one is the future
of MEMS in Medical field seems to be bright in next few decades and the other reasons is
BioMEMS lifesaving abilities. The 2nd reason is the main motto of my investment in this field.
Apart from this, the manufacturing of the this item that I have chosen above would give me a good
return back, the thought made by me in the field of BioMEMS, which could likely be protected to
nature and human wellbeing.
