Tone paper - roll-to-roll printed loudspeaker paper
pmTUC has developed a technology which allows the manufacturing of loudspeakers solely by means of conventional mass printing technologies on flexible substrates like foil or even paper. More precisely, we are talking about printed piezoelectric loudspeakers, i.e. a piezoelectric crystal transfers an applied AC voltage to a mechanical deformation and a vibration of the whole substrate. If the frequency of the AC signal is in the frequency range of 20 Hz to 20 kHz, audible sound is generated.
In our case a piezoelectric polymer is sandwiched between two organic electrodes, i.e. we have truly fully plastic speakers without magnets. All layers can be printed step by step on a substrate but thanks to new developments during the last three years, we are now able to integrate all electronic layers within a special paper – the tone paper – or shorter T-paper – was born making it possible to print on both sides of the paper color pictures or whatever you are used to print (or write) on paper. The printed electronics part keeps hidden and invisible.
At the starting point of this project, the realisation of the T-paper is based on a semi-automatic sheetfed process with low efficiency and throughput. However, first applications could be successfully demonstrated like the T-book in 2015 – a unique photo book with speaking images.
Now, main aim of the VIP+ project T-paper is to transfer the inefficient sheetfed manufacturing to a high-throughput roll-to-roll pilot line at one of pmTUC’s R2R printing presses. This includes the development and validation of a stable R2R printing process of all functional layers, the inline polarisation of the piezoelectric material but also post-press technologies like lamination and folding.

LowCostEPS - Low-cost emergency power system based on printed smart supercars
Nowadays, in India electrical power is a moste essential item. To solve the problem of power failures, a standard solution is the installation of a diesel generator supported by a battery stack to provide power in the moment of the blackout. These batteries are costly, the service life is limited and often they are the most unreliable component in the whole emergency power system (EPS).
To solve this problem, the Indo-German project consortium has the intention to create a new LowCostEPS based on mass-printed smart supercars for small and medium sized applications in the power range of 2.5 to 10 kVA. The LowCostEPS should bridge the time of power interruption until the existing diesel generator provides enough power to run a proper energy supply again. The core idea of the proposed project is to use conventional printing methods, such as gravure, offset or flexographic printing, for the production of low-cost supercaps. Conventional printing methods are well-known for their high productivity and cost-effectiveness due to the mass-production possibility.

A holistic, scenario-independent, situation-awareness and guidance system for sustaining the Active Evacuation Route for large crowds (eVACUATE)
In the EU IP project eVACUATE, the intelligent fusion of sensors, geospatial and contextual information, with advanced multi-scale crowd behaviour detection and recognition will be developed. The structured fusion of sensing information with dynamic estimated uncertainties on behaviour predictions will advance eVACUATE crowd dynamic models; and virtual reality simulations of crowds in confined environments. A service oriented Decision-Support System shall be developed to dynamically distribute on-demand evacuation information to emergency management actors as the crisis unfolds. Decision-makers at the command posts, first responders, front-line stewards and volunteers receive real-time situation aware information of updated evacuation strategies using robust and resilient eVACUATE information and communication infrastructure. Smart spaces of electronic, audio and other mobile devices shall be connected to the integrated system to provide safer evacuation routings for people. The eVACUATE system performance and scalability will be validated in five distinct scenarios involving incidents with large crowd at various venues with the requirements of evacuation time reductions and increases of safety and security. These are: 1) Underground stations in Bilbao and 2) Marseille; 3) Real Sociedad Footbal Stadium in San Sebastian, 4) Athens International Airport and 5) a STX Cruiseship.
