2. System Introduction
The TE-CORE /RF is a complete thermo-
powered, selfsuffi
The TE-CORE /RF is based on an Energy Harvesting
module with power management function, which
converts locally available waste heat thermoelectrically to
indefinite free electric energy.cient wireless sensor node
system (WSN).

3. Features

440-2 V1.4.1., iM222A Zigbee Network Processor of
IMST, operating in 2.4 GHz ISM band

4. Aplikasi
 Maintenance-free wireless sensors and actuators:
 Wireless sensors and sensor networks (WSN)
 Autonomous intelligent valves
 Industrial process control & condition monitoring
 Thermal event logging and alerting
 Smart metering
 Remote sensing & tracking

5. Design
 The Energy Harvesting module of the TE-CORE /RF
operates from a heat (or cold) thermal energy source. The
TGP’s aluminum top side, its thermal input, is supposed to
be attached to the heat source. The thickness of the thermal
input acts as a spacer to protect the PCB and to ensure a
thermal separation between the hot and cold sides; i.e.
optimizing energy harvesting performance through
suppression of thermal ‘cross talk’

6. Absolute Maximum Ratings
 Please ensure that during operation of the TE-CORE
/RF system the below maximum ratings, see below, are
not exceeded:

7. Concept of Energy Harvesting
 Energy harvesting systems generally consist of: energy collection
elements, conversion hardware and power conditioning and
storage devices as shown in Figure.7. Power output per unit mass
or volume i.e. power/energy density is a key performance unit for
the collection elements. The harvested power must be converted
to electricity and conditioned to an appropriate form for either
charging the system batteries or powering the connected load
directly.
 Load impedance matching between the energy collectors/energy
sources and storage elements / connected to the load is
necessary to maximize the usage of the scavenged energy.
Appropriate electronic circuitry for power conditioning and load
impedance matching may be available commercially or may
require custom design and fabrication.

8. Block diagram energy harvesting
 To ensure continuity in the load operation even when the external
power source is temporarily unavailable, the excess energy harnessed
has to be stored either in a rechargeable battery or electrochemical
double layer capacitors, also known as supercapacitors/ultracapacitors.
The power conditioning electronic circuits in the energy harvesting
system are designed based on the energy harvesting input energy
sources and the connected output loads, hence different types of power
conditioning circuit designs have been proposed to bridge between the
source and the load. It is worth noting that the design of the energy
harvesting system to power the sensor node in the WSN may differ
from one application to another application because of the variations
in the load requirements and the differences in

9. Benefits of Energy Harvesting
Energy harvesting provides numerous benefits to the end user and some of the major
benefits about EH suitable for WSN are stated and elaborated in the following list.
Energy harvesting solutions can:
 Reduce the dependency on battery power. With the advancement of
microelectronics technology, the power consumption of the sensor nodes are
getting lesser and lesser, hence harvested ambient/environmental energy may be
sufficient to eliminate battery completely.
 Reduce installation cost. Self-powered wireless sensor nodes do not require power
cables wiring and conduits, hence they are very easy to install and they also reduce
the heavy installation cost.
 Reduce maintenance cost. Energy harvesting allows for the sensor nodes to function
unattended once deployed and eliminates service visits to replace batteries.
 Provide sensing and actuation capabilities in hard-to-access hazardous
environments on a continuous basis.
 Provide long-term solutions. A reliable self-powered sensor node will remain
functional virtually as long as the ambient energy is available. Self-powered sensor
nodes are perfectly suited for long-term applications looking at decades of
monitoring.
 Reduce environmental impact. Energy harvesting can eliminate the need for
millions on batteries and energy costs of battery replacements.
