We report on the development of an enhanced and robust microfluidic plant chip-based growth and monitoring system for high-throughput phenotyping of Arabidopsis thaliana. The system consists of multiple vertical plant chips, a microfluidic hormone concentration gradient generator, multiple simple gravity pumps, and a robotic arm with a stereoscope for plant imaging. We validate this system by phenotyping...
We present the first MEMS Solid State Gas Generator (SSGG) for use as a deorbit technology, in conjunction with inflation balloons, for Small-Satellites (<180kg mass). The total system, named the Solid State Inflation Balloon (SSIB), is being designed as a simple, reliable, scalable, low-cost, non-propulsive deorbit system. Small-Sats in Low Earth Orbit (LEO) are required, through multi-national...
This paper reports a new hybrid energy harvesting approach which combines triboelectricity and piezoelectricity based on low-frequency (less than 5 Hz, such as environmental vibrations) stochastic resonance. A vibration configuration was well designed to enhance the conversion efficiency of mechanical energy to electricity via the stochastic vibration mechanism. Furthermore, the electric output performance...
We present a new transparent high-performance triboelectric microgenerator (TEMG) based on an emerging material, silk fibroin. Silk fibroin has a strong ability to lose electrons and occupies a top-level positive position in the triboelectric series. It thus significantly contributes to the performance enhancement of TEMG. To efficiently harvest energy from airflow, a channel-shaped TEMG was developed...
