Abstract: Disclosed herein is a device, system, and method for a trickle charging system of non-inductive voltage boost (NVB) converter with built-in auto-dummy-load (ADL) for wide-range of charge storage devices i.e. small button-cell type batteries and super-caps using micro power pyro-electricity at Si-MOS sub-threshold voltage. A VLSI configuration of the system is also disclosed in embodiments. The system converts the pyro-electric material at MOS sub-threshold 0.37V for optimizing to the battery charging level at 1.45V. This system was proven at hardware level and found to be 98.8% power efficient. The designed IC can charge independently without any external components for up to 1 uW max, but able to charge up to 20 uA with external components. Thus it is considered to be a very versatile design.

Abstract: Disclosed herein is a non-Inductive voltage boost-converter (NVBC) for micro-power energy harvesting systems for energy storage and delivery applications. Current devices deliver a wide-range of micro-power having only up to 0.8V peak-voltage, but nominally 0.45V in lab test conditions. This voltage is not adequate in charging storage cells such as rechargeable batteries and also driving electronic circuits. Technology is in demand where a boost-converter must operate at MOS sub-threshold voltage (Sub-VTH) limits. Disclosed herein is a novel NVBC device that has eliminated the need of an inductor coil and associated high-speed switching circuits; thus achieving higher efficiency. The disclosed invention applies a simple self-synchronizing technique to adapt the NVBC automatically to the low-frequency energy signal of a pyroelectric device. A novel NVBC is presented for stabilized output of NVBC (S-NVBC). In an embodiment, the S-NVBC achieves an efficiency of 86%.

Abstract: A pyroelectric reference device comprising an equivalent electronic circuit that produces the similar electrical characteristics of a pyroelectric material sample device, under discrete thermal conditions in laser energy lab setup, is disclosed herein. The device presented here facilitates running experiments without the need of special equipment and/or setups using the real pyroelectric device in thermal radiation environments for harvesting micro power energy.

Abstract: An infrared imaging system is described which includes a pyro-optic sensor for receiving a thermal image on one of its sides, the sensor exhibiting a substantial change in refractive index in responses to changes in its temperature. A light beam is projected onto a second side of the sensor, the beam being selectively, locally reflected by the sensor in accordance with local changes in its refractive index. A receiver detects the reflected beam and responds to the reflectance changes to derive a visible image of the thermal image.The pyro-optic sensor comprises a sandwich structure which includes a film of energy absorbant material upon which the thermal image is received; a thin film of thermal-optic material; and a supporting layer which includes an optically transparent foam positioned next to the pyro-optic material on the side at which is directed an interrogating light beam.
