Printed Electronics PE in the last decades have gained more and more importance. Applications in important fields are possible which before were equipped with State-of-the-Art SoA devices having a hard case housing and a rigid printed circuit board. Insofar PE devices are much more environmentally friendly than SoA devices.
In total small electronic devices show an increasing demand because more and more things must be controlled. That concerns especially:
- Logistics, RFID
- Smard Card for financial applications and others
- Transportation trackers, like T-Logger for documenting the cooling chain
- Health monitoring in the hospitals as well as for hobby sports
- …. And of course, Internet-of-Things IoT
These devices are equipped with conducting path, antenna, printed transistors OTFT, OLED and OPV. Todo almost all applications are passive. The µChips on it can only operate if an energy source like Radio-Frequency RF field or a light source is close to it. For an extended operation the PE device needs an energy source, like Printed Batteries PB or Printed Supercapacitors PSc. Preferably these energy sources are also printed.
The development of PB was done, among others, at VARTA. They developed a PB using the electrochemical system Zinc-Manganese Dioxide-Chloride Electrolyte ZnC. This system is easy to be printed – this will be explained more in detail in the talk. But also, PSc have a serious chance because they are > 1000x rechargeable.
In the talk it will be shown which properties the PB and PSc should have and how they can be integrated. Furthermore, it will be shown how the energy sources can be perfectly adapted to the application. This is important to:
- Save materials, costs
- Make them more environmentally friendly
- Make them smaller, thinner, more flexible
Finally, it will be described how important a worldwide cooperation is in this field. There is expertise from many disciplines requested, along the value chain from materials, processes to the end-users.
