Building Electric Energy Sensing

Stick-on Electric Energy Monitoring Systems

Introduction: In this project, we are developing a stick-on electric energy monitoring system for residential and commercial buildings. The system leverages novel remote sensing technologies to accurately reconstruct electric currents and voltages from the magnetic field and electric field measurements. Giant

Granular Radio EnErgy-sensing Node (GREEN)

GREEN CAD

This device implements a mesh network. Conceivable applications include distributed environmental sensing, household monitoring and any other space where many small sensor nodes are required. The current use case being explored is circuit-breaker panel monitoring using GMR magnetic sensors to measure

Non-Intrusive Testing of Underground Power Distribution Cables

Concentric Neutrals Project

Power distribution companies rely on miles of aging underground cables to distribute electricity with no cost-effective way of telling which are in danger of failing. One of the problems that can arise in these cables is the failure of current

Battery-Replacement Scale Energy Harvesting From HVAC Flows

HVAC

Create an energy scavenging device that produces over 100 µW of power in air flows of 2-5 m/s. These operating conditions are characteristic of HVAC systems, and the power output would be sufficient to run a low-power wireless sensor node

Natural Gas Pipeline Sensors

MEMS pressure sensor

New low-cost natural-gas pipeline sensors can be deployed widely to inspect the underground pipelines that convey and store natural gas, often within densely populated regions. More inspections and more data mean earlier warning of potential problems.
