Welcome to the EnHANTs Project!
In this project we are developing Energy-Harvesting Active Networked Tags (EnHANTs). EnHANTs are small, flexible, and energetically self-reliant devices that can be attached to objects that are traditionally not networked (e.g., books, furniture, walls, doors, toys, keys, clothing, and produce), thereby providing the infrastructure for various novel tracking applications. Examples of these applications include locating misplaced items, continuous monitoring of objects (items in a store, boxes in transit), and determining locations of disaster survivors.
Recent advances in ultra-low-power wireless communications, ultra-wideband (UWB) circuit design, and organic electronic harvesting techniques will enable the realization of EnHANTs in the near future. In order for EnHANTs to rely on harvested energy, they have to spend significantly less energy than Bluetooth, Zigbee, and IEEE 802.15.4a devices. Moreover, the harvesting components and the ultra-low-power physical layer have special characteristics whose implications on the higher layers have yet to be studied (e.g., when using ultra-low-power circuits, the energy required to receive a bit is significantly higher than the energy required to transmit a bit).
The objective of the project is to design hardware, algorithms, and software to enable the realization of EnHANTs. This interdisciplinary project includes 5 PIs in the departments of Electrical Engineering and Computer Science at Columbia University with expertise in energy-harvesting devices and techniques, ultra-low power integrated circuits, and energy efficient communications and networking protocols.
The project is supported in part by:

Prof. Gil Zussman received a Marie Curie International Incoming Fellowship from the European Commission 7th Framework Programme (FP7). This competitive fellowship will support a long term visit to the School of Computer Science in Tel Aviv University, Israel.
Within the Marie Curie project, Prof. Zussman will focus on research in the area of design and performance evaluation of resource allocation algorithms for energy harvesting networks. This work will build on recent progress within the EnHANTs project.
On December 5th, 2013, The EnHANTs demo was presented by Earvin Caceres and Robert Margolies to 13 high school students as part of a tour of Columbia’s facilities through Harlem Educational Activities Fund's College Quest Program. the goal of the visit was to excite students about the field of physics by exposing them to the equipment used in research facilities.

Four different publications and presentations have been recently contributed by different members of the EnHANTs project:
- Allerton Conference on Communication, Control, and Computing: A paper co-authored by Xiaodong Wang titled " was recently present at the Allerton Conference on Communication, Control, and Computing at the University of Illinois at Urbana-Champaign.
- IEEE GlobalSIP 2013: A paper authored by John Sarik, Kanghwan Kim, Maria Gorlatova, John Kymissis, and Gil Zussman titled "More than Meets the Eye - A Portable Measurement Unit for Characterizing Light Energy Availability" was recently present at the GlobalSIP 2013 Symposium on Energy Harvesting and Green Wireless Communications in Austin, Texas.
- IEEE GlobalSIP 2013: Professor Gil Zussman gave a keynote talk at IEEE GlobalSIP 2013 Symposium on Energy Harvesting and Green Wireless Communications titled “Energy Harvesting Active Networked Tags (EnHANTs) — Measurements, Algorithms, and Prototyping”.
- Columbia University: Maria Gorlatova gave an invited talk titled "Characterizing New Environmental Energy Sources for the Internet of Things" at an undergraduate computer science and statistics STATW100 seminar at Columbia. The talk was focused on light and motion energy measurement studies and characterizations.
EnHants project contributors Maria Gorlatova and Jiasi Chen were among the top 40 female graduate students and postdoctoral scholars invited to participate in the 2013 MIT Rising Stars in EECS, the annual workshop that brings together top women in EECS for two days of scientific discussions and informal sessions aimed at navigating early stages of the academic career.
