New Monitor Finds Electrical Failures Before They Happen
Cambridge, MA — A new system de- vised by researchers at MIT can monitor the behavior of all electric devices within a building, ship or fac- tory, determining which ones are in use at any given time and whether any are showing signs of an immi- nent failure. When tested on a U.S. Coast Guard cutter, the system pin- pointed a motor with burnt-out wiring that could have led to a seri- ous onboard fire.

The new sensor, whose read- ings can be monitored on an easy-to- use graphic display called a NILM (non-intrusive load monitoring) dashboard, was described in the March issue of IEEE Transactions on Industrial Informatics, in a paper by MIT professor of electrical engi- neering Steven Leeb, recent gradu- ate Andre Aboulian MS ‘18, and sev- en others at MIT, the U.S. Coast
Guard, and the U.S. Naval Academy. The system uses a sensor that is attached to the outside of an elec- trical wire at a single point, without requiring any cutting or splicing of wires. From that single point, it can sense the flow of current in the adja- cent wire, and detect the distinctive “signatures” of each motor, pump or piece of equipment in the circuit by analyzing tiny, unique fluctuations in the voltage and current whenever a device switches on or off. The sys- tem can also be used to monitor ener- gy usage, to identify possible efficien- cy improvements and determine when and where devices are in use or sitting idle.
The technology is especially well-suited for relatively small, con- tained electrical systems, such as those serving a small ship, building, or factory with a limited number of devices to monitor. In a series of tests on a U.S. Coast Guard cutter based in Boston, the system provided a dramatic demonstration.
About 20 different motors and devices were being tracked by a sin- gle dashboard, connected to two dif- ferent sensors, on the cutter USCGC Spencer. The sensors, which in this case had a hard-wired connection, showed that an anomalous amount

Munich, Germany — Transistors are everywhere, but they often operate only within a restricted current range. Ludwig-Maxmilians-Univer- sitaet (LMU) physicists have now de- veloped an organic transistor that functions under both low and high currents.
The pressure to reduce econom- ic and environmental costs in circuit design has caused regular inorganic semiconductor dimensions of below 100 nanometers to become standard. However, organic semiconductors have not been able to keep up. Their performance, in terms of charge-car- rier transport, is considerably worse. Organic structures offer other advantages. They can be printed easily on an industrial scale, their material costs are lower and they can be applied transparently to flex- ible surfaces.
Thomas Weitz, LMU physics professor and member of the Nano- systems Initiative Munich, and his team are working intensively on the optimization of organic transistors. In their latest publication in Nature Nanotechnology, they describe the fabrication of transistors with an un- usual structure, which are tiny, pow- erful and versatile. By carefully tai- loring a small set of parameters dur- ing the production process, they have been able to design nanoscale devices for high or low current densities. The heart of the innovative concept is the use of an atypical geometry, which al- so facilitates assembly of the nanoscopic transistors.
