LIGNA featured by IpXchange
We’re excited to share this new video from IpXchange, diving into how Ligna’s ultra-thin supercapacitors are reshaping the future of flexible electronics. From smart cards with fingerprint sensors to medical patches and wearables, our sustainable energy storage solutions are opening up new possibilities—where traditional batteries and capacitors fall short.
What’s in the video:
- Supercapacitors vs Capacitors vs Batteries
- How LIGNA’s ultra-thin supercapacitors fit into flexible, compact, and wearable electronics
- Smart card applications: on-card displays, fingerprint scanners, secure data storage
- How these capacitors work when NFC power isn’t available
- Why LIGNA’s forestry-sourced lignin cathode is a breakthrough in sustainability
These supercapacitors come in a form factor thinner than half a millimetre, yet still pack up to 1.2 farads of capacitance at 2.7V. They’re built for scenarios where traditional capacitors or batteries just can’t go—think payment cards, hotel keys, wearables, and other flexible or disposable electronics.
Engineering Benefits:
- Ultra-low-profile: under 0.5mm
- High capacitance: 60mF and 1.2F available
- Safe: Non-flammable, non-toxic materials
- Sustainable: Made using lignin, a waste product from the forestry industry
- Ideal for intermittent power, low-voltage energy harvesting, and short-term backup power
Key use cases:
- Secure bank cards with display & biometrics
- NFC-enabled hotel cards with dynamic data
- Medical patches and flexible wearables
- Thin embedded energy storage for low-power IoT
