How can we store the energy we harvest?
Batteries are bulky and their finite life-time and low power density can be a problem when they are embedded in inaccessible, permanent structures or when very quick charging and discharging is required.
Supercapacitors store electrochemical energy and are ideal for energy harvesting applications. Their life expectancy is extended to millions of cycles while maintaining higher power densities that can be fully charged or discharged in a matter of seconds.
What we are doing
In our research group we inkjet-print low cost, high performance supercapacitors to meet the energy storage demands of wearable electronics, internet-of-things and wireless sensor networks.
The digital nature of inkjet-printing enables innumerable patterns and designs to be implemented efficiently, as well as allowing for the fabrication of multifunctional energy storage units.
