They are not tattoos.they don't contain any ink nor involve piercing through skin.they can stick to the skin as band aid and consists of sensors.in addition to sensors wireless networking capability provided with which contrlolling can be done from remote computer or smartphone.

3. INTRODUCTION
• Commonly used epidermal tattoos:
DIGITAL TATTOO ANIMATED TATTOO
ELECTRONIC TATTOO

4. WHAT IS ELECTRONIC TATTOO?
 Stretchable , ultrathin electronic patch
 Forms human-machine interfaces
 Small ,flexible circuit device
 Sticks comfortably to skin as temporary tattoo

5. HISTORY
• Rogers Research group at the university of
illionois at urban –campaign has given us
stick-on electronic tattoos

6. TRADITION APPROACH
• EES technology came in 1929
• Bulk electrodes were mounted on skin via tapes,strapes etc
• Circuit boards, power supplies and communication system are
basic parts
• Poorly suited for practical application outside lab

7. CONSTRUCTION:
• Circuit is made of sillicon
• Circuit has filamentary serpentine shape
• It allows them to bend,twist,scrunch and stretch
• Approximate dimensions of tattoo circuit 2.1cm*3.1*5microns

8. COMPONENTS AND WORKING

9. THREE STATES OF EES
Multifunctional EES onskin:
unreformed(left),
compressed(middle),
stretched(right)

10. SLAPPING OF ELECTRONIC TATTOO
• Vandewalls interaction allows the tattoo to stick on to the skin
• Allows the tattoo to stay in position without any glue
• As the vanderwall forces are weak it can be removed easily

11. MULTI-FUNCTIONAL OPERATIONS
Electroencephalograms
(EEGS)
Electrocardiograms
(ECGS)
Electromyograms
(EMGS)
Stimulated computer
game control via neck
EMG measured by EES
Multifunctional
operation

12. ECG MEASUREMENT

13. EMG MEASUREMENT

14. EEG MEASUREMENT

15. COMPUTER GAMES CONTROLLING
• it performs voice controlled video games with 90% accuracy
• With a tatto attached to throat
• It can transform commmands like
up
down
left
right
stop
go

16. DUARABILTY TEST
• A EES is mounted on cheek and elbow for upto
24 hours and to verify compatibility
• It remained intact and no redness or
inflamation was observed even after subject
had lunch
• But tattoo attached to elbow will be cracked
with in 8 hours

17. APPLICATIONS
• Controls computer games
• Monitors brain signals,heart-attacks & muscle
movements
• In millitary operations
• Health of prematured babies

18. ADVANTAGES
• Light weight
• Small in volume
• Measures electropsychological signals
• No mechanical visibility
• No itching or irritation
• Easily removed

19. DISADVANTAGES
• Continuous emition of dead cells doesnot take
place
• Transpiration doesn’t take properly

20. IN FUTURE
• We might interact with smartphones and
computers simply by using our minds
• We may turn on lights in home just by thinking
about it

21. CONCLUSION
