What is sensitive skin?
It is a large area flexible array of sensors, with data
processing capabilities, with the ability to sense
the surroundings.
It make possible the use of unsupervised machine
in our midst.
15. Devices For Sensitive Skin
1.Flexible or deformable
2.Power storage
3.Deployed 2-D array
4.Smaller array
5. Self sensing ability
6.Measure distance to objects
7.Studies in h/w architecture
8.Unique properties
16. Large - Area Electronics
1.Organic electronics and optoelectronics on
flexible substrates.
OTFT
17. 2. Thin Film MEMS
Thin film micro electromechanical (MEMS) devices on
plastic substrate demonstrate that mechanical sensors
can be built on flexible substrate .
3. Nanostructures
Ultra large area ICs embedded into electrotextiles
18. Manufacturing Of Large Area Sensitive
Skin
Printing techniques
1.Direct Printing
2.Laser Writing
3.Nanoimprinting
21. LASER WRITING
Laser writing is combined with MAPLE process:
1.Electronic circuit patterns are formed
2.Move the receiving substrate 1 beam dia.
3.Assemble to get desired pattern
22. Nanoimprinting
Principle
A thickness is created which
is transferred through resist
layer via on O2 plasma
based etching process.

lithography (NIL)
24. ADVANTAGES
Reversal of negative impacts of machines
Reduction in weight and thickness
Can be rolled
FIR AND IIR filters conserves the battery power.
Friendly to environment
25. DISADVANTAGES
Skin be able to conform to arbitrary shapes.
Able to flex, bend and stretch
Properties of fusion vary when components fail
or repaired.
26. APPLICATIONS
1.Human skin or Wearable skin
2.Sensitive skin for machines
3.Environmental sensitive skin
4.Actuated sensitive skin
27. FUTURE SCOPE
Develop new inexpensive consumer electronics
Displays, printers
Store and information
Ranging from medicine and biology to machine
industry and defense
space exploration, mine detection
28. CONCLUSION
Sensitive skin will make it possible to have unsupervised machinery
in unstructured, unpredictable surroundings. It will make the
machine cautious and eco friendly. It is an enabling technology with
far reaching application The state of art in the areas that are basic to
the development of skin technology shows that highly efficient
devices are feasible. All this non withstanding the fact that the
existing prototypes are clumsy, have low resolution, accuracy and
reliability, and are not yet ready for commercialization.
