LASSIE-FP7 (Large Area Solid State Intelligent Efficient Luminaires), a European project, is pushing back the boundaries in the lighting industry. The module developed by the consortium led by CSEM, a Swiss micro- and nanotechnology research institute, is reported to strengthen the range of tools available to the European lighting industry and offers an innovative solution providing exceptional light quality and colour rendering that stands the test of time.

In science, sometimes the best discoveries come when you’re exploring something else entirely. That’s the case with recent findings from the US National Institute of Standards and Technology (NIST), where a research team has come up with a way to build safe, nontoxic gold wires onto flexible, thin plastic film. Their demonstration potentially clears the path for a host of wearable electronic devices that monitor our health.
The new IR Topled D5140 from German-based Osram Opto Semiconductors is reported to require considerably less pc board space than before. It enables more compact sensors to be produced for monitoring fitness levels, for example in fitness armbands. The spectral sensitivity of the D5140 has been optimised for visible light and allows precise heart rate measurements using red or green light. The component is also ideal as an ambient light sensor.
