Supercapacitors bring many benefits to applications where a fast discharge is required, and provide a much higher energy density than electrolytic capacitors at a much lower physical footprint. However, supercapacitors are still produced as discreet components and are still bulky for certain applications. In this work we demonstrate the integration of supercapacitors into the fabric of flexible printed circuits. Flexible printed circuits (FPCs) typically consist of layers of Cu and polyimide and are commonplace in most electronic apparatus, typically as interconnectors onto which components are attached. We demonstrate a supercapacitor which fully integrates with the FPC production process and can be easily manufactured by any FPC producer. The embedded supercapacitor provides low ESR energy storage without the need for an additional discrete component. An areal capacitance of ~200-250mF/cm2 has been demonstrated, and the resulting device is tolerant to flexibility. Reflow solder tolerant devices are currently in test. A few practical use examples will be shown.

Cambridge University Eco Racing (CUER) is a 60 strong student organisation that designs, build and races solar powered vehicles.
Since their founding in 2007, they have been the UK's number one for solar vehicle development and achieved 2,047km on solar power at the World Solar Challenge in 2015 with their latest vehicle, Evolution.
Their team mission is to inspire as well as innovate. Through exploring new areas of ultra-efficient vehicle technology, they aim to challenge the accepted concept for solar vehicles with their unique design. In addition they provide students at Cambridge University with a learning platform for applied engineering, strategic planning and leadership in the real world.
