Energy harvesting is an enabling technology for realizing an ambient power supply for wireless sensor nodes and mobile devices. By using flexible photovolta-ic cells and piezoelectric films, we can readily harvest ambient energy if flexible energy harvesters can be realized. Conventional silicon circuits, however, are not best suited to realizing flexible(More)
—This paper presents a 95 mV startup-voltage step-up DC-DC converter for energy harvesting applications. The capac-itor pass-on scheme enables operation of the system from an input voltage of 95 mV without using additional off-chip components. To compensate for the die-to-die process variation, post-fabrication threshold voltage trimming is applied to(More)
—A shoe insole pedometer, which consists of a piezo-electric energy harvester and a 2 V organic pedometer circuit, has been developed as a first step toward the application of flexible large-area energy harvesting. A pseudo-CMOS 14 bit step counter records the number of steps up to 16383 steps using the harvested power. To increase the noise margin of the(More)
Understanding the interconnectivity of organisms among different habitats is a key requirement for generating effective management plans in coastal ecosystems, particularly when determining component habitat structures in marine protected areas. To elucidate the patterns of habitat use by fishes among coral, seagrass, and mangrove habitats, and between(More)
* Blind quantum computation protocols allow a user with limited quantum technology to delegate an intractable computation to a quantum server while keeping the computation perfectly secret. Whereas in some protocols a user can verify that calculated outcomes are correct, a third party cannot do this, which allows a dishonest user or owner to benefit(More)
Anemonefishes are popular model species for research on population connectivity via larval dispersal, and understanding this connectivity is beneficial when designing marine protected areas. We developed 15 microsatellite markers for two anemonefishes, Amphiprion frenatus and Amphiprion perideraion. Of these 15 markers, 10 worked well for both species,(More)
