MIDE Demo Day is an open event for the Aalto University staff and other interested parties. Saha’s doors open at 12 pm. We serve cupcakes, coffee and demos. Vote for the best demo and win an evening in a restaurant for two!

1. Manikin Therminator for demonstrating temperature distribution on human skin (4D Space)
Manikin 'Therminator' and infra-red camera to show the temperature distribution. The manikin control is based on a model of human thermoregulation that can predict the human skin temperature accurately. The measurements of the environment is fed to the manikin and the manikin adjusts the skin temperature as a human being. The benefit from that accurate simulation of human physical and thermal presence is to evaluate the thermal comfort and indoor wellbeing.

2. UbiQloud - Social Smart Space Gateway (4D Space)
The end user solution integrates cloud based social data with a mobile application.The system combines multiple embedded NFC and RFID hardware technologies, enabling monitoring of people flow, energy usage and waste production. The development opens a gateway for developing web of things.

3. Dye-sensitized solar cells (CNB-E)
New material innovations, like carbon nanotubes and nanobuds studied in the CNB-E project, can help developing cheaper and more efficient and durable solar cells, but only if their properties are correctly engineered to match with the performance requirements set by the application. In our stand we display the key materials and components used in the dye-sensitized solar cells, discuss their key functional properties, and demonstrate them in action.

4. Thermoacoustic carbon nanotube loudspeakers (CNB-E)
Thin and flexible electronic devices such as loudspeakers are ideal for future embedded smart surfaces. The CNB-E project demonstrates how thermoacoustic carbon nanotube loudspeakers can be fabricated using a simple printing method. In the thermoacoustic effect, an alternating current heats up the nanotubes. This adiabatically heats up the surrounding air, producing the pressure variations we perceive as sound. The speaker element consists of a transparent nanotube film only a few hundred nanometers thick, and does not contain any magnetic or moving parts. A prototype fabricated from a larger surface area nanotube film enables greater sound levels.

5. Wood structural modelling (E-Wood)
E-Wood project seeks to understand how mechanical energy is absorbed by the wood material on the molecular, supra-molecular and cellular levels. The researcher's demo shows how the wood structure can be modelled and how different types of wood behave at the micro- and macro-scales under various modes of loading and varying conditions. The ultimate target of the E-Wood project is to facilitate changes in the mechanical wood defibrating and machining industries by radically decreasing their use of energy.

6. A self-pressurized combustion process (Exergy)
In a normal combustion chamber, where the process takes place at constant pressure, the entropy generation rate is large which means also a great exergy loss and lower efficiency. The project's researchers have already shown, that theoretically an adiabatic reversible combustion could be self-pressurized, even up to several hundred bars, without a compressor and with the same outlet temperature of the flue gas. To improve the combustion process efficiency, the researchers study the use of an oxygen-ion conducting membrane in a self-pressurized oxygen combustion in practice.

7. How the LED efficiency can exceed 100 % (HighLight)
Solid state lighting based on wide bandgap semiconductor LEDs is expected to provide high efficiency lighting solutions and large savings in global electricity consumption in the next 5-10 years. The HighLight project develops inorganic LED prototypes based on new device geometries and materials. At the demo stand you can explore the operational principle, maximum efficiency and fabrication methods of a LED and observe LED structures, new bipolar diffusion assisted test structures and electrodeposition of surface coatings through a microscope.

8. Cutting half the heavy working machine’s energy consumption (HybLab)
The HybLab project team research hybrid electric systems for heavy working machines. The researchers have already demonstrated how the energy consumption of an working machine can be cut into half of current level. The project brings a scale model explaining the energy buffering concept in a lifting operation, diesel engine and purpose build generator for hybrid work machine and software for simulation the early phase in product development process.

9. Carry-on hydrogen supply (IPPES)
Target of the IPPES project is to develop a charger or use extender of electronic devices. The system presented at the Demo Day combines an electrolysis cell for production of hydrogen gas and a fuel cell for converting the produced gas to electricity. Hydrogen is produced by electrolysis of methanol, which requires significantly less energy than electrolysis of water. Additionally, the reaction conditions are mild: ambient temperature and pressure. A small part of the energy generated by the fuel cell is utilized by the electrolyzer for the gas production. The excess energy, the net energy, is used to power an appliance.

10. Wireless structural health monitoring system (ISMO)
The ISMO project has developed a structural health monitoring system, which uses wireless sensors to collect information and measure vibration in the structures, such as bridges and buildings. The wireless measurement system can easily be installed also on large structures. Using the collected vibration data, changes in the structure, such as damages, can be detected by analyzing the excited frequencies. The wireless sensors run a measurement program with pre-defined interval, collecting high frequency vibration data, and communicates the data using the efficient and fast A-stack protocol for analysis at a computer. Some computations can also be done at the sensor to reduce the required data to transmit.

11. User studies with social media services in Otaniemi, Nairobi, Beijing and California (OtaSizzle)
OtaSizzle project has developed an open experimentation environment for testing mobile social media services. It started as a living lab for users in Otaniemi. The project creates prototype mobile social media service platforms and studies them with extensive field tests, coupled with quantitative measurements and qualitative analysis. OtaSizzle has also extended its research to Nairobi, Beijing and California, and has produced a spin-off company ShareTribe. At their demo stand you can disucss the user studies made and see what the ShareTribe founders have created.

12. Urban strategy table (UI-ART)
The Urban strategy table is a multi-touch interface that allows a group of users to interact with a computational urban growth model. Users can try different urban planning interventions and see their effects on the urban growth model.

13. Adaptive speech synthesis (UI-ART)
GlottHMM is a novel statistical speech synthesis method capable of generating natural sounding synthetic speech. At the Demo Day the researchers will demonstrate how different speaking styles (breathy, normal, and the so called Lombard speech that natural speakers use when they speak in noise) can be synthesized with GlottHMM.

14. GeoBois - augmented reality mobile phone game (UI-ART)
GeoBoids is a game designed to combine fast-paced, arcade-style action with large-scale physical user movement for exergaming. The concept is that geometric creatures from the eighth dimension are visible in our dimension using a specially equipped device (the player’s smartphone). They congregate in flocks in certain areas of our world. The player’s goal is to travel to those places identified on a map, and collect GeoBoids, in order to help them return to their own dimension. Each species of GeoBoid has its own properties, including color, shape, flying pattern, active time of day/night, and affinities.

15. Virtual work environments for enhancing business and innovation (VinCo)
The VinCo research project studied how collaboration and communication in global distributed teams and in fully virtual environments can enhance business and innovation. At the moment, the researchers continue their work with benchmarking different kinds of workspace requirements. In the Demo Day you can test several purpose specific spaces.

16. The first Finnish nanosatellite (Aalto-1)
Aalto-1 is a student satellite project, the first in Finland. The Aalto-1 project started in the beginning of 2010, when a group of students made a feasibility study of the satellite in the framework of the Space Technology special assignment course. Since then the project has created significant excitement among students and teachers alike. At the Aalto-1 demo stand you can study the satellite's mechanical mock-up model and see what kind of payload it will carry to the space in 2014.
