Introduction to Energy Harvesting
There is an Ocean of Energy all around us
This is where EnOcean got its name
The Concept of energy harvesting is not new
Michael Faraday discovered the operating principle of electromagnetic
generators 1832. The principle, later called Faraday's law, is that an
electromotive force is generated in an electrical conductor that
encircles a varying magnetic flux. This principal can use water to drive
a dynamo and generate power
Windmills used wind to convert ambient energy to mechanical force

EnOcean Equipment Profiles Learn Telegram from a 4BS sensor
The EEP (EnOcean Equipment Profile) is an agreed telegram profile
number that points to an interpretation table needed in the receiver.
To keep the radio telegram as short as possible the sensor will inform the
receiver during the teach-in procedure about its characteristics.
For interoperability a standard for this teach-in procedure and for the later
exchange of data has been defined.

Attainable power from thermoelectric converters depending on size and temperature difference
Thermal Energy (1)
PELTIER / SEEBECK effect
A thermoelectric device creates a voltage
when there is a different temperature on 2
junctions of 2 metals, a property discovered
by Seebeck in 1821.
Conversely when a voltage is applied, it creates
a temperature difference (known as the Peltier
effect).
There are a number of low cost Peltier
elements available and these can be used ‘in
reverse’ as generators for small wireless
monitors.
Harvesting Heat
Heat
Cold ( heat sink)
N P - +
A heat source will drive electrons
in the n-type element toward the
cooler region, creating a current
through the circuit.
Holes in the p-type element will
then flow in the direction of the
current. The current can then be
used to power a load.

© EnOcean GmbH > Energy Harvesting Wireless Technology > Jan-13 Page 71
Kurukshetra 13
The voltage generated from Peltier
elements are very low requiring
innovative DC-DC conversion
The ECT310, is a low-cost ultra low
voltage DC/DC converter that uses a
highly innovative blocking oscillator
design.
2+ Kelvin temperature difference on the
Peltier device gives around 20 mV to 50
mV corresponding to an output voltage
range between 3V to 4 V from the ECT
310.

Designing external sensors / electronic circuits, key requirements:
1. Ideally passive sensor types (e.g. thermistor, photo-resistor, not always possible!) 2. Device operating voltages (IF APL.) as low as possible, e.g. 1.8 V or lower 3. Totally operating current as low as possible, e.g. <1 mA or less (nA…µA) 4. Short measurement time (default sensor settling time e.g. <2 ms after power-up)
EnOcean devices: some important design hints
Radio propagation range considerations, key element antenna:
1. Indoor propagation, energy requirements, frequencies, compliance, link budget, 2. Environment analyze, installation, antenna choice, design, verification, tools 3. Interference effects: e.g. power supply importance, rules for clean layout
1. Energy harvesting sources / availability: solar, thermal, movement: devices, limits 2. Energy storage elements: requirements, specifications, limitations, alternatives 3. Energy balance: importance of the application specific wake-up settings 4. Energy management recommendations, approaches, technological limitations

Current security - ID Authentication
Principle ID concept
Every telegram sent contains a 32bit ID
identifying the sender
Security measures to protect against
misuse
Unique Module ID
ID management and burning at
manufacturing site
EnOcean firmware ensures you cannot
replicate the unique Chip ID
Special Purpose ID
pre-programmed BaseID
up to 128 IDs from BaseID+0 .. BaseID+127
BaseID can be modified up to 10 times

SECURITY Enhancement
Rolling Code – Fraud Resistant
against reply attack
Purpose: avoiding an eavesdropper
recording the transmission and
“unlocking” the receiver
Strategy: changing a rolling code
included in the telegram
Encryption – Tap Proof against
eavesdropper
Purpose: obscuring the information being
sent in the air
Strategy: encrypted data “unreadable”
for eavesdropper

Interoperable
Algorithms are public
The secret of security is the used key
Profiles will be defined for interpreting secure messages
Compatible with existing Dolphin hardware
SECURITY Benefits

Flexible
Different encryption algorithms selectable
Rolling code does not need to be transmitted in telegram
MAC algorithm can be selected and added
Strategies are combinable
Future proof
New algorithms can be added without breaking the concept for
Encryption
Rolling code
Message Authentication code
Strategies against new attack types can be added
