Description 267-273
Underwater environment is the new frontier
for major future discovery for the benefits of the world at large. The vastness
of the oceans mirrored the vast potentials that lie beneath it. In order for
scientist and researchers to explore these vast resources, newer and better
sensing technology is pertinent. Of course, any sensor module would not be of
any use if there are no reliable platforms to take them to the bottom of the
oceans or any water column. Currently, there are underwater robotic platforms
that can navigate down to more than 6000 meters. But, there are limitations
which need to be addressed. In general, the advancement of sensing technology
has always preceded most, if not all, major discoveries in the field of science
and technology. The efforts into developing sensors must take into
consideration the inherent environmental limitations for underwater
applications such as the corrosive nature of sea-water, bio-fouling, limited
energy resource module, pressure resistant enclosure, data transfer reliability
and the dynamic nature of the ocean itself. The research into producing
acceptable sensor system/modules will require close international
collaborations. The whole range of potential measurement and sensing
requirements also may disrupt the proper development of a robust and reliable
sensing system/module. Underwater sensor technology can be divided into the
acoustic or non-acoustic based sensing. The major problem of acoustic-based sensors is that they are very prone to noise.
Because acoustic signal are mechanically-actuated signal, the dynamic nature of
the underwater medium disrupts the signal quality. On the other hand, the
non-acoustic sensors are very application-specific, and must be tailored made
for specific applications. The utilizations of MEMs-based underwater
sensor system are a major future scope of research. MEMs-based sensor will
optimize the cost of material and energy, particularly. One other potential
dimension of underwater sensor development is the bio-inspired system approach.
The existing biological system around us, especially in the oceans, is a rich
depository for ideas and solutions to the
man-made problems. Bio-inspired sensor system is not just about trying to
imitate the living system, but synergize the current available technology with
what nature is showing.
