ABSTRACT
Skinplex is the key to Ambient Intelligence and covers two basic functions:
Active communication of data over the skin
Passive sensing the change of an electrical field by man
Skinplex is an enabling technology of future near field man-machine communication. A
base technology providing new possibilities in all areas of daily life. It can both, support existing
applications and offer solutions for new products. An ID-Tag or badge which is carried at or near
the body serves as identification media. Already during the approach the ID-code can be
evaluated. The door lock is activated if the person touches the handle.
The reading distance higher then with RFID, depending on the capacitive area of the
Skinplex receiver. No expensive and complicated antenna and strong power supplies. A Touch-
Panel recognizes the person and the Skinplex transmitter over the capacitive near-field. It reads
the information already ahead of being touched. Skinplex detects approach and touch of humans.
This sensor function can be used for jamming protection or as a switch. The sensor ability and
communication can be combined.

CHAPTER 1
INTRODUCTION
Skinplex is a technology that allows for active (wireless) data communication using the skin as a
transmitter. It can also passively detect touch or near touch situations. Thus it falls into the
domain of Near Field Communication (NFC) and it can be used in the creation of a Personal
Area Network (PAN) or Body Area Network (BAN). Its main claims to fame are that is has alarger range than RFID and that the whole body can be used as transmitter making at an effective
tool in personal identification.
The passive Skinplex system is also very interesting for energy efficiency purposes in
many appliances as it can automatically shut them down as soon as the user has let go (for
instance in a wireless computer mouse or advanced TV remote). Also it is a more reliable sensor
technology as it harder to activate accidentally as can happen with IR proximity sensors or
accelerometers.

2.1 WORKING
Skinplex Technology envisions a world where electronic devices can be controlled
simply and effectively using reliable grip and proximity detection, and using gestures with just
the wave of your hand. Skinsresistance includes a real part and an imaginary part, for our data
transfer we use a frequency with which the imaginary part disappears.
Transmissions operate at 195 kHz. Range advantage" over RFID and NFC (50 cm).
Skinplex is an enabling technology of future near field man-machine communication. A
base technology providing new possibilities in all areas of daily life. It can both, support existing
applications and offer solutions for new products.
An ID-Tag or badge which is carried at or near the body serves as identification media.
Already during the approach the ID-code can be evaluated. The door lock is activated if the
person touches the handle. The reading distance higher then with RFID, depending on the
capacitive area of the Skinplex receiver. No expensive and complicated antenna and strong
power supplies.
A Touch-Panel recognizes the person and the Skinplex transmitter over the capacitive
near-field. It reads the information already ahead of being touched.
Skinplex detects approach and touch of humans. This sensor function can be used for
jamming protection or as a switch. The sensor ability and communication can be combined.

2.2. Detection:
All you need to use Skinplex as a human sensor is a Skinplex receiver and a capacitive
area. The approach or touch can quantitatively and qualitatively be registered and processed.
Skinplex converts these elementary human actions in practical applications:
Jamming Protection and Anti-Trapping
Burglar Alarm
Intelligent Switches
Human Sensor
2.3. Communication:
For the next step, the communication, you need a Skinplex transmitter and a receiver.
The transmitter has a unique ID, just like a RFID-transponder.

The data is transmitted if you approach or touch a Skinplex receiver or the connected
capacitive area.
The Skinplex Technology can be used in automotive, automation, telecommunication,
security and data-collection. Skinplex provides new solutions and products :
Security Management and Access Control
Data-Collection
Ambient Intelligence
Operator Authentication

CHAPTER 3
WORKING PRINCIPLES
In short: Skinplex uses a small device that is in (near) contact with the skin
transmits a signal over the whole surface of the users body.

This signal can be read by a touch panel (the communication with the on body device
is already established before touch occurs) and can control a broad range of functions within
the device that has the touch panel.
The touch panel uses alternating electrical fields which change (increase) when the
electric field of the human body is introduced into the system.
The device that is in near contact with the skin can influence the electric field of the
human body in such a way that it can be used as a data transmitter.
The input of the system is therefore an electrical field and the output is an electrical
signal which can be interpreted and processed by a computer.

SYSTEM USING SKINPLEX TECHNOLOGY
4.1: ULTRA LOW POWER PROXIMITY SYSTEM
Provides solution to wake-up and power down devices on the approach and departure ofthe user.
Average Current consumption is typically in the self discharging range of batteries.

Fig.4.2: Internal arrangement of electrodes
A sensor device is provided, with a first electrode structure comprising a transmitting
electrode(SE), a compensation electrode(KE) and reception electrode(EE) and with a second
electrode structure comprisings a number of field sensing electrodes(FE).
The first and second electrode structure are coupled with an evaluating device(A). The
evaluating device comprises signal generator(g) for supplying the transmitting electrode and
compensation electrode with an alternating electrical signal (WS1,WS2).
The electrodes are arranged in relation to each other in such a way that a first alternating
electrical field emmited at the transmitting electrode may be coupled into the reception
electrode and into at least one of the field sensing electrodes and a second alternating

electrical field emitted at the compensation electrode(KE) may be coupled substantially only
into the reception electrode(EE).Also a method is provided for detecting an encompassing of
a hand-held device by a user.
4.2: ZERO POWER SENSOR SYSTEM
The SKINPLEX zeropower sensor system is a quasi powerless near field transpondersystem for touchless sensing applications in rough environments.
The system consists of one server and several zeropower clients. The zeropower system is ideal for spatial distributed multi-key and sensor
applications

4.2.1 Functional Description
The zeropower server provides on its electrodes an electrical field in the range of 80to 140 kHz.
The E-field and ground supplied zeropower client powers up and modulates the fieldon its electrodes with a programmable identification code.
4.3: GESTIC GESTURE DETECTION SYSTEM...
Gestures, i.e. movements with your hand are one of the most intuitive ways to controlgames
. The SKINPLEX Gesture Detection System consists of 4 capacitance sensitiveelectrodes, a hardware front end and a sophisticated software algorithm that calculates
the gesture movement.

CONCLUSION
How well the Skinplex technology works in practice remains to be seen The usual factors of performance, price, device compatibility, and ergonomics still need
to be fleshed out.
The technology itself is intriguing, and may have even more applications we can'tenvision yet.
There is no clue on when skinplex might hit the market. It has been reported this may not appear in commercial devices for at least 2 years. Skinplex is a very interesting technology. But its fate will ultimately depend on how
committed Microsoft is to making it a commercial reality and how soon.
