Low Cost, High Efficiency Mobile Solar Sensor Developed

A new, highly efficient and low-cost mobile solar sensor for field analysis of solar cell performance has been developed by researchers at the U.S. Naval Research Laboratory (NRL) Electronics Science and Technology Division. The new sensor, which costs about $20 USD to produce, takes aim at the growing number of mobile solar power units, and the device can serve to measure and analyze solar cell irradiance performance and spectral distribution, which can help to improve both efficiency of systems and to forecast power supplies. “We have invented a novel minimum size, ultra-low power spectral radiometer unit with integrated data storage… read more

Generating Heat With Human Bodies


An ambitious, and definitely unique, plan is underway in Paris, France to generate heat for an apartment complex above the Paris metro. Waiting passengers’ collective body heat will generate heat to the complex above, along with heat from passing trains, the rail, etc. It’s an experiment right now, but if it proves useful, the system may be implemented more widely, and might not be limited just to the Paris metro. Using heat exchangers, researchers will tap into human caloric heat and transform it into usable heat for the tenants above. It won’t be a stand-alone system, and will be used… read more

Swimming with sensors

Scientific breakthroughs in nanotechnology have taken electronics to the next level by making the circuit smaller and smarter, but a professor at the University of California is proving that he can design circuits which can be pushed, pulled and even used under water. Thin film electrochemical sensors are directly printed on a flexible wetsuit by the team led by Joseph Wang paving the way for water resistive electronic sensors which has a potential application under water. With funding from the U.S. Navy and with the help of some members of his team who like to surf, Wang and team designed… read more
