Introduction: Using Transparent Silicone Glue and Conductive Threads to Make Flexible LEDs Circuit
Runner Up in the
Soft Circuit Contest
Step 1: Materials for Mounting the LEDs Circuit
.The circuit consists of 3 flat square LEDs, connected to the Conductive Thread.
. The anode and cathode of the LEDs were cut and bent.
. Three ends of the conductive thread were twisted together so as to improve the conductivity.
Step 2: Making the LEDs Circuit
. The Anode and Cathode of the LEDs were bent over the conductive thread.
. The LEDs were connected in Parallel.
Step 3: Testing the LEDS Circuit
. The Circuit was tested by connecting to a DC power supply
Step 4: Sealing the Circuit in the Silicone Paste
. A rectangular piece of Aluminium, of size 8 cm by 5 cm with 3mm thickness, was used as a mould.
. The circuit was sealed in the wet silicone paste.
Step 5: Removing the Silicone From the Mould
. Once dried, the silicone was easily removed from the mould.
. The silicone is very adhesive and normally will glue to most materials.
. The surface of the aluminium mould was made very smooth and this prevented the silicone to adhere to the surface.
Step 6: Testing the Silicone LEDs Circuit
. The silicone circuit was further connected to a power supply and illuminated instantly creating a nice strong glow.
Step 7: Bending the Silicone Circuit
. It was interesting to note that the silicone could be bent to almost 360 degrees on either side.
. While bending the silicone circuit, the LEDs inside, continued to stay lit.
. The silicone circuit was hand-washed several times.
. After each washing and drying, it was tested by connecting to the power supply.
. Amazingly, the circuit lit up.
. The sample was further washed two more times and the results were all the same.
. All LEDs lit up opening a wider scope for more experiments.
We have a be nice policy.
