Plessey Semiconductors

Plessey's High Brightness LEDs

Solid State Lighting (SSL), powered by Light Emitting Diodes (LEDs), is the key technology for reducing the many terawatts of electrical energy consumed and the many tons of greenhouse gases produced when generating light around the world. One of the main barriers for the migration to LED powered solutions is the initial investment cost as the LEDs are manufactured using exotic, expensive material substrates. Plessey is the market leader in bringing LEDs into the lower cost, mainstream world of semiconductors, with its pioneering GaN-on-Silicon technology.

LEDs are made using Gallium Nitride (GaN), a semiconductor material that has specific light emitting properties. Plessey's MaGICâ„¢ (Manufactured on GaN-on-Si I/C) process is an innovative approach to LED production that will enable a leading and sustainable position for many years to come. The basis of this approach is to exploit the cost benefit of using standard Silicon substrates on which the GaN layer is grown. Plessey's patented technology solves the physical mismatch issues that result from growing GaN-on-Silicon. Furthermore, utilising the inherent advantages of a large wafer scale silicon based approach, Plessey is able to exploit advanced packaging technology from the IC industry and is bringing to the market intelligent squared LED (i2LED) products that will enable high performance cost effective SSL solutions.

Epic is Plessey's multi Award winning sensor

Plessey has developed a sensor that will ultimately change our lives forever. Its ability to manufacture an ultra low cost version provides enormous opportunities for use in high volume markets. Epic's electric potential sensing technology has the capability of being used in any number of applications but initially Plessey has focussed on developing products for the Automotive, Sports Fitness and Healthcare sectors.

Disruptive EPIC sensor with multiple proven applications

  • High sensitivity electric potential sensor that can be used in either contact or non-contact mode
  • Contact mode: measures bio-electric signals like ECG, EMG, EOG and EEG
  • Non-contact mode: measures disruption in the electric field caused by human body movement enabling
  • Proximity sensing
  • Movement Sensing
  • Gesture recognition
