1. 1. Active Infrared light power supply for indoor wireless sensor nodes

   University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

   Author : Jialei Chen; [2020]
   Keywords : Energy Harvesting; IR; WSN; Photovoltaic;

   Abstract : In order to expand the energy source in energy harvesting, this thesis explores the feasibility of using infrared light source as the energy source. Firstly, the thesis investigated the current energy harvesting solution and the way of using infrared light energy, and determined the use of crystalline solar panels as energy harvesters. READ MORE

3. 2. Electrical performance study of organic photovoltaics for indoor applications : with potential in Internet of Things devices

   University essay from Karlstads universitet

   Author : August Andersson; [2020]
   Keywords : Indoor light harvesting; Internet of things IoT ; Organic Solar cell; Organic photovolaic;

   Abstract : The evolution of the internet of things (IoT) opens the market opportunity for organic photovoltaic cells, especially for indoor applications where the lifetime of the organic cells is longer than outdoor. For example, IoT requires off-grid energy sources for many devices with low power consumption. READ MORE

4. 3. Battery-free Visible Light Sensing

   University essay from Uppsala universitet/Avdelningen för datorteknik

   Author : Andreas Soleiman; [2019]
   Keywords : Networked embedded systems; Visible light sensing; RF backscatter; Energy harvesting;

   Abstract : In this thesis, we show that it is possible to design a battery-free light sensing system that can sense and communicate hand gestures while operating fully on harvested power from indoor light. We present two main innovations that push our system to tens of microwatts of power to enable battery-free operation. READ MORE

5. 4. On The Importance of Light Source Classification in Indoor Light Energy Harvesting

   University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

   Author : Ye Zhang; [2018]
   Keywords : Indoor light energy; classifier model; different light condition; influence factor; energy evaluation.;

   Abstract : Indoor light energy harvesting plays an important role in field of renewable energy. Indoor lighting condition is usually described by level of illumination. However, measured data alone does not by classification of different light sources, result is not representative. READ MORE

6. 5. An Automatic Simulation System for Solar Panel under Indoor Conditions

   University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktion

   Author : Zhefu Ji; [2017]
   Keywords : Modeling; Solar panel; Energy harvesting;

   Abstract : Energy harvesting system is a system which could convert ambient energy into electrical power, its output depends on the energy availability of ambient conditions. For indoor condition, light is a typical available energy, and solar panel could be used to harvest it. READ MORE
