This paper presents a boost-type energy-harvesting battery charger IC that can maintain high efficiencies over a wide range of input power. In other words, the IC has a fast response to achieve 94% peak efficiency at high input power conditions, yet dissipates only 14.7nW quiescent power to achieve a net positive charging at low input power conditions. The key to this fast, low-power operation is...
This paper proposes an algorithm that can maximize the total harvested energy of a single-inductor buck-boost converter operating with multiple input energy sources. It does so by dynamically adjusting the turn-on times and allocating the available time slots for the individual input sources in such a way that all the sources require equal turn-off times for the buck-boost converter to meet the zero-current...
A piezoelectric-based energy harvesting and power management IC that can supply a total energy of 160-μJ at 2.5V from a single button-pressing action to realize a batteryless wireless remote switch (BWS) is presented. The IC uses a 6:1 series-parallel switched-capacitor converter and a bias-flipping inductor to match the impedance, down-convert the voltage, and maximize the total energy harvested...
Improved glucagon-like peptide-1 (GLP-1) receptor activation is considered one of the most effective targets for antidiabetic therapy. For this purpose, we modified the GLP-1 analog of exendin-4 using two fatty acids (FA) either lauric acid (LUA, C12) or palmitic acid (PAA, C16) at its two lysine residues, to produce; Lys 12 -FA-Exendin-4 (FA-M2), Lys 27 -FA-Exendin-4 (FA-M1), or Lys...
Robot system is widely used in unmanned exploration or investigation because it can be dangerous or impossible to explore a certain unknown area such as distant planet. For this purpose, highly intelligent single robot systems are generally used. But thinking of disabled situation, a lot of swarm-bots can be alternative to a single highly intelligent robot. This paper reports an implementation of...
