This paper presents a simulation-based study for characterizing and analyzing the performance of a commercially available thermoelectric cooler (TEC) as a generator for harvesting heat energy along with a commercial-off-the-shelf (COTS) power management integrated circuit (PMIC); LTC3108. In this model, the transformation of heat was considered in terms of an electrical circuit simulation perspective, where temperature experienced by TEC on both cold and hot sides was incorporated with voltage supply as Vth and Vtc in the circuit. When it comes to modeling a system in a simulation program with an integrated circuit emphasis (SPICE) like environment, the selection of thermoelectric generator (TEG) and extraction methods are not straightforward as well as the lack of information from manufacturer’s datasheets can limit the grip over the analysis parameters of the module. Therefore, it is mandatory to create a prototype before implementing it over a physical system for energy harvesting circuit (EHC) optimization. The major goal was to establish the basis for devising the thermal energy scavenging based Internet of Things (IoT) system with two configurations of voltage settings for the same TEG model. This study measured the data in terms of current, voltage, series of resistive loads and various temperature gradients for generating the required power. These generated power levels from EHC prototype were able to sustain the available IoT component’s power requirement, hence it could be considered for the implementation of IoT based applications.

Abstract. This research work presents the simulation based study of a commercial solar cell for analyzing the real-time behavior of a PV module. The mathematical modelling is based on Equivalent circuit of the solar cell and demonstrating the practical approach for using the single diode five parameters (IM5P) mechanism. This research involves purely mathematical formulation to extract the unknown parameters of PV cell by applying the Lambert W function. The I -V and P -V characteristics are emulated under different temperature and radiation levels by using the Linear Technology's LTSpice simulator.

Micro-scale energy harvesting solutions are highly demanded globally in almost every field.Specifically, when it comes for a cell phone battery life. The imbalanced situation between battery technology and cell phone evolution is getting worse. However the efficient system is needed which is able to charge a cell phone when we are off from the power source.The researchers put forwards the attention towards the readily available energy sources to be harvested for charging purpose.For making such efforts, number of solutions have been proposed but many hurdles lies in it which includes the design, compatibility and most importantly the different parameters of every cell phone device.This paper demonstrates the specifications of different cell phone models and a datasheet is produced which includes the minimum output power requirement during standby and talk time.

A stroke characterized as a sudden onset of symptoms that can cause a wide range of different problems. If the stroke affecting the right side of the brain the problems occurs on the left side of the body and inversely (affecting the left side of the brain, the problems occurs on the right side). Stroke victims often lose proper function of at least one hand and fingers .With exercises, the survivors have been changed to recover their hand functions, in this paper we are going through the most effective technologies based on stroke hand rehabilitation with the devices which could do that exercises. During the last few years, interest has been growing for the hand rehabilitation technologies, FES "function electrical assimilation" has been widely used to restore upper limb functions in people with hand disability and it has improved their ability to perform their activities of daily living (ADL)
