Sensitive skin is a large-area, containingflexible array of sensors with dataprocessing capabilities
Sensitive skin represent a new paradigm inSensing & control.
They will allow us to fullfill our dreams formachines sensitives to their surroundings&operating in unstructured environment.
The application of sensitive skin will berealized,ranging from medicine and biologyto the machine industry and defense.

It holds embedded sensors and related signalprocessing hardware.
It needs to be flexible enough for attaching itto the outer surfaces of machines with movingparts and flexible joints.
Wiring must keep its integrity when SensitiveSkin is stretched or wrinkled
SKIN MATERIALS

What materials might be used?
How can we make an interconnection networkthat can flex and bend?
How can we physically combinesensors/intelligence/actuators with theinterconnect substrate?

HYBRID APPROACH
ADDING SENSING /INTELLIGENCE
The hybrid concept is similar to that usedin printed circuit
Finished chips are attached to a network
of wiring.

INTEGRATED APPROACH
directly integrate the devices for thesensors, intelligence, etc directly ontothe substrate with the interconnect
approach has a systems advantageover the hybrid approach

12/21
A very attractive long-term approach mergingdifferent concepts .
A fabric woven of fibers, where the fibers are notconventional fibers but rather very thin strips of
devices and interconnect on flexible substrates,such as thin plastic or metal foils
DISTRIBUTED INTELLIGENCE APPROACH
-

Flexible or deformable
Power by wire photovoltaics, RF, fuel cells,micro engines, or from energy harvesting -
(skin-integrated mechanical powergenerators).
Self-sensing ability of the skin is highlydesirable.
Can be tiled or cut without losing its sensingand control functionality.

Need for throwing away as much information aspossible as early as possible.
Used in order to achieve low power in wireless sensorsystems.
A whole set of higher-order DSP algorithms are likely tobe used in these systems. Examples include:
Event detection and classification
Data fusion
Distributed beam-forming
Novelty detection
DATA REDUCTION

Signal processing means traditional signalprocessing (and more specifically DSP)
Distributed and robust algorithms for
communications and processing are used.
DATA PROCESSING

19/21
Sensitive skin is a large array of sensorsembedded in a flexible, stretchable, and/orfoldable substrate
Enable us to have unsupervised machinery inunstructured, unpredictable surroundings.
It presents a new paradigm in sensing andcontrol.
It is an enabling technology with far reachingapplications, from medicine and biology toindustry and defense.
