Kickoff eit unibo

  1. 1. Department of Electrical, Electronic and Information Engineering (DEI) University of Bologna Micrel Group Davide Brunelli, University of Bologna and University of Trento Email: davide.brunelli@unibo.it , davide.brunelli@unitn.it
  2. 2. Expertise of UNIBO (Micrel Lab)• The group has multi-year experience in software development forpower aware embedded systems and design of environmentalenergy harvesters.Particular emphasis are on the following topics:- multi-source scavenging Example by combining heterogeneous energy sources: - light irradiance and photovoltaic + - thermal energy - kinetic energy (human movements Kinetic Energy and Photovoltaic and vibrations) ….
  3. 3. Expertise of UNIBO (Micrel Lab)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
  4. 4. Expertise of UNIBO (Micrel Lab)Particular emphasis are on the following topics (cont’d) :-Energy-aware design, energy saving MAC protocols andCross-layer energy optimization for wireless sensor networkprotocols. Environmental aware routing must be able to exploit exposed nodes and take into account distance between nodes
  5. 5. Enhanced Power Unit possible Architecture Energy Transducers Kinetic Energy, Photovoltaic … Power Unit Monitor Conversion Electronics Measures energy Take raw electrical signal from and battery transducer and convert it to a usable DC charging status, voltage elaborates energy predictions and Energy Storage and Delivery provides Receives energy from conversion information to the electronics and stores it (SuperCap, powered system batteries, etc. ) Regulates the output voltage and current. UNITN sensing and elaboration platform 5
  6. 6. UNIBO Contribution• To design and implement efficient multi-source harvesters with smart interface to extend the autonomy of the wearable for UNITN nodes UNITN Node - Energy Status Power Supply - Policies for Efficient Energy Use Smart Power Unit UNIBO - Energy Harveter -Batteries• 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
  7. 7. 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”.
  8. 8. Wind Harvesting Wind Turbine W24TH Sensor Node Multi-source Sensor nodes with Wind Energy Harvester Harvesters deployed in Rome (metro B2 tunnel) April 2012Wind Energy Harvester and sensor node in a lab test
  9. 9. Carrier OverviewGENESI  The 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  http://genesi.di.uniroma1.it  Project Reference:257916
