imec and CMST, its associated lab at Ghent University, have developed thermoplastically deformable electronics technology that is said to enable the creation of low cost 2.5D free form rigid electronic objects. The technology is being tested by Philips for use in LED lamp carriers, a downlight luminaire and a omnidirectional lightsource.
The approach is based on what are described as ‘meander shaped interconnects’. This, say the partners, is a robust technique that creates dynamically stretchable elastic electronic circuits – including LEDs – which can then be embedded in thermoplastic polymers. Although created on a flat substrate, using standard PCB production equipment, the circuit can then be shaped using such techniques such as vacuum forming, high pressure forming or even injection moulding.
Imec and CMST believe deformable electronic circuits will not only enable novel lamp designs, but also novel ambient intelligence and wearable products.
