This paper presents an airflow energy harvester coupling (i) fluttering phenomena to turn airflows kinetic power into mechanical oscillations of a flexible membrane and (ii) an electret-based electrostatic converter to turn the resulting mechanical oscillations into electricity. The device is able to work down to 5.5m/s and harvests up to 330μW at 9m/s with a surface of 70mm×55mm. It has been combined...
This paper presents a power management circuit implementing a Synchronous Electric Charge Extraction on piezoelectric energy harvesters based on a flyback architecture. The novelty of this circuit lies in its ability to handle multiple energy harvesters operating at different frequencies and different output voltages with a single and standard flyback coupled inductor. The power harvested by the various...
We report the first silicon integrated graphene optical electro-absorption modulator capable of 10Gb/s modulation speed. We demonstrate low insertion loss and low drive voltage combined with broadband and athermal operation in a compact hybrid graphene-Si device, outperforming Si(Ge) optical modulators for future chip-level optical interconnect application.
Encyclopedias of regulatory genomic elements provide a foundation for research in areas such as disease diagnosis, disease treatment, and crop enhancement. The construction of complete encyclopedias of organism-specific genomic elements involved in gene regulation remains a significant challenge. To address this problem, the authors present novel bioinformatics strategies for exploring the word landscapes...
