Embedded: Energy harvesting demonstration
Avnet Abacus and Cymbet have teamed up to demonstrate energy harvesting with solid state batteries at Embedded World, Nuremburg, using Texas Instruments, Atmel and Silicon Labs microcontroller and wireless reference designs.
The demonstrations on Avnet Abacus stand (Hall 1, Stand 249) include: flexible photovoltaic cells; thermal gradient harvesting using a thermoelectric harvester; vibration harvesting using a piezoelectric transducer; and RF induction charging.
Cymbet evaluation kits and reference designs for all these harvesters are available from Avnet Abacus.
There is also a real time clock (RTC) power hold-over circuit based on a Cymbet CBC-EVAL-06 evaluation kit which combines an EnerChip CBC3112 ‘uninterruptible PSU in a Chip’ with the Microcrystal RV-2123-C2 – claimed to be the world’s smallest integrated RTC module.
“Cymbet energy harvesting kits are now interoperable with the Silicon Labs RF-to-USB2 RD wireless demonstration kit, available from Avnet Memec,” said Avnet, “enabling designers to experiment with all the ambient energy harvesting to power SiLabs Si1014 wireless MCU nodes.”
Visitors to the Cymbet stand will be able to see Texas Instruments’ CC2540 Bluetooth low energy (BLE) evaluation kit powered by the Cymbet’s EnerCard solar energy harvesting module – on which the Cymbet’s CBC915 energy processor implements maximum peak power tracking to optimise power extraction.
The TI BLE kit is available from distributors Silica and EBV.
