Interview with IpXchange at Embedded World 2024

At Embedded World 2024 we were interviewed by ipXchange’s Eamon Standing about our products and their various use cases.

“Ligna Energy’s supercapacitors push the bio-based and recyclable composition of such devices to the limit. This makes for much more sustainable supercapacitors that are not toxic to humans or the environment when an end product is eventually disposed of. Ligna Energy also produces its supercapacitors in a pouch-type format, meaning that far less material is used overall, adding to the sustainability of its devices.

Additionally, Ligna Energy’s sustainable supercapacitors are produced in such a way that aims for the lowest CO₂ emissions, further minimising impact on the environment at a time where many would say that we are at a tipping point.

That said, Ligna Energy’s supercapacitors still pack a punch, with its most popular device – the S-Power 2S – boasting 1.2 F capacitance and supporting up to 350 mA peak currents.

John then shows us some ambient IoT demonstrations of Ligna Energy’s sustainable supercapacitor in action. The first combines Ligna Energy’s technology with an Epishine PV cell and a Senseair sensor to provide CO₂ and temperature warnings on a small display.

The second uses the sustainable supercapacitor as a power source for an art tracker and tamper detector.

John also shows the smaller sustainable supercapacitor in an RF energy harvesting reference card. Though this is simply a proof of concept, it shows how compact or thin you can make ambient IoT devices by using Ligna Energy’s sustainable supercapacitors rather than bulky cylindrical alternatives.”
