• The group has multi-year experience in software development for power aware embedded systems and design of environmental energy harvesters.
Particular emphasis are on the following topics:
- multi-source scavenging
by combining heterogeneous energy sources:
- light irradiance and photovoltaic
- thermal energy
- kinetic energy (human movements
and vibrations)
….
Expertise of UNIBO (Micrel Lab)
Example
Kinetic Energy and Photovoltaic

Particular emphasis are on the following topics (cont’d) :
- Distributed energy management
Enviromental and Human Energy
is different from battery energy
•Availability varies in time– Sometimes is scarce– sometime over-abundant
•Availability varies in space– Different nodes get different energy
•Somehow repetitive & predictable– Opportunity for predictive and adaptive management techniques
Expertise of UNIBO (Micrel Lab)
Particular emphasis are on the following topics (cont’d) :
-Energy-aware design, energy saving MAC protocols and Cross-layer energy optimization for wireless sensor network protocols.
Expertise of UNIBO (Micrel Lab)
Environmental aware routing must be able to exploit exposed nodes and take into account distance
between nodes

Conversion ElectronicsTake raw electrical signal from
transducer and convert it to a usable DC voltage
Energy Storage and DeliveryReceives energy from conversion
electronics and stores it (SuperCap, batteries, etc. ) Regulates the output
voltage and current.
Energy TransducersKinetic Energy, Photovoltaic …
UNITN sensing and elaboration platform
Power Unit Monitor
Measures energy and battery
charging status, elaborates energy
predictions and provides
information to the powered system
• To design and implement efficient multi-source harvesters with smart interface to extend the autonomy of the wearable for UNITN nodes
• To develop harvesting policies which:- define when and how power is harvested;- regulate when and how to activate batteries; - estimate in advance the energy availability

Harvesting in WSN-Tunnels (UNIBO)[Living Lab]
To develop and integrate Energy Harvesting capabilities to pre-existent WSN for monitoring in tunnels.
Innovative platforms of Wind energy Scavenger will be used in a real working scenarios controllable by developers and users, in the tunnel in Trento configured as “living lab”.

Carrier Overview
GENESIThe GENESI project proposes research addressing all the critical barriers
and challenges that prevent the application of WSNs and CPS for monitoring structures, buildings and spaces
Wireless sensor nodes will be capable of achieving virtual infinite lifetime through a well-balanced combination of cutting edge technologies such as energy harvesting from multiple sources and fuel cell power supply
