Würth Elektronik eiSos and Analog Devices are exhibiting “Gleanergy” – the jointly developed energy harvesting demo kit – at embedded world. It will be on display both at the Analog Devices booth as well as on the Würth Elektronik eiSos booth. Since its launch, the development platform has opened up the possibility of using several sources of ambient energy to operate a wireless sensor node as a means of extending battery life.
The “Gleanergy” demo kit – the name combines “glean” and “energy” – contains a thermogenerator, solar cells and an input for a piezoelectric generator. On the Energy Harvesting Power Board there is also a Li-ion rechargeable battery, a normal Li battery, ceramic capacitors and a super capacitor, as well as several switching controller ICs. With the Gleanergy Kit, developers can test scenarios to run a battery-operated device with the aid of ambient energy sources for as long as possible without maintenance.
The application board contains an ARM Cortex-M3 processor, a SmartMesh network interface and an E-Ink display for indicating the battery charge level, etc. It also includes two coulomb counters for measuring the energy of the microprocessor. A wireless module in the form of a USB dongle allows data to be transmitted from the sensors connected to the demo kit onto a PC and displayed.
The Würth Elektronik eiSos US subsidiary, Wurth Electronics Midcom, is staging an “Off The Clock Design Challenge” – those interested can sign up for before March 23, 2018 and develop their idea into an energy harvesting application based on the Gleanergy Kit.
