CHANGING THE WAY WE POWER OUR WEARABLE ELECTRONICS
Carica leverages human motion to deliver battery-free wearable electronics.
By converting mechanical movements into electrical energy,
we can extend the battery life of our current wearable electronics
and even eliminate the need of a battery.
What we do
Energy Harvesting
Human motion driven energy harvesters can power wearable electronics without ever needing to plug them in to charge.
Energy Storage
Stretchable micro-supercapacitors can be used to extend the charge cycle of rechargeable batteries or used as an alternative to a battery when used with energy harvesters.
Why Harvest Mechanical Energy?
The fact that our energy harvesting power supplies allow users to continuously wear their wearable devices without having to worry about taking them off to charge is great. No more missed data or forgetting to charge your device. While those are attractive benefits, we think one of the most important reasons to harvest mechanical energy is to conserve our natural resources. Since our power supplies don’t need batteries, we can help reduce the amount of lithium, cobalt and global mining that is directly attributed to traditional chemical batteries.
Technology
How it Works
It is a very simple concept. As a person walks the energy harvester produces electricity which quickly charges the micro-supercapacitors that power wearable electronics.
Energy Harvester
Energy Generation
As a person walks, two different materials come in contact then separate in the energy harvester. This produces contact electrification and generates a charge between the two materials.
Conversion Circuit
Energy Conversion
Due to the intermitted mechanical energy generated when a person walks, the energy harvester produces an alternating current. Using a specially designed circuit, we are able to convert the alternating current to direct current. This circuit allows for an energy conversion efficiency of over 85%.
Micro-Supercapacitors
Energy Storage
Micro-supercapacitors are used to store the energy. Unlike batteries, supercapacitors can charge and discharge quickly resulting in faster charging time. Our micro-supercapacitors have a capacitance of roughly 8 mF with 93% capacitance retention after 10,000 charge-discharge cycles at a current density of .57 μWh cm-2.
