A new concept device designed by Wan Xuan Lim and Tan Xueling Jane called the Eco-pulse looks to inform appliance users of their energy use by displaying a heartbeat-like pulse based on electromagnetic fields and amplifying them much like a stethoscope.
Owners would hold the Eco-pulse up to an appliance, noting the different colors and amplitudes displayed, and then press a capture button on the right side. The data would be stored until the user uploads the information into Eco-pulse software that completes a report showing users where to best conserve energy. The device would also detect the so-called “vampire power” products use when in stand-by mode. The Eco-pulse seems to be built off a previous idea from Lim, which he called Intelligent Power Meter.
The idea is quite novel, and may become a valuable to home owners as more and more smart meters roll out across the globe. Since many products don’t already give up-to-date information about their energy use, the Eco-pulse might be a good way for owners to learn about their older electronics.
