Tears Sensor

I made a tears sensor for my recent project “Five Facts About Tears”. This tears sensor can detect tears and map tears into sound.

Five Facts About Tears is a video for art performance with five series of speculative wearable installations which have interaction with human extreme emotion carrier–tears. You can find the videohere . My webisite .

Material List:

Conductive Tape;

Arduino Nano / Arduino Uno;

* DFPlayer Mini;

9V Battery;

Speaker;

Breadboard;

Audience: Who wants to make art or design piece that needs to detect their tears :)

Step 1: Design the Circuit on Face

Step 2: Try the Circut

I used Arduino, breadboard, some jumper wires, buzzer, and conductive tape which already have been cut to make this work. The water connects the gap inside the conductive tape. So when water drop, the buzzer ring. And buzzer rings louder when water gets more.

The code is here:

int piezoPin = 8;
void setup() {

}

void loop() {

tone( 8, 2000, 500);

delay(1000);

}

Step 3: Design the Tattoo and Vinyl Cut the Conductive Tape

I used a Vinyl Cutter (Silhouette Portrait 2) to cut a 2-inch width conductive tape.

Step 4: Attach the Conductive Tattoo on Face and Set Up Others

Step 5: Wait for Your Tears
