12. Skin Electronics#

This week I worked on skin electronics by using an extensiometric gauge positioned on a finger.

Research#

A strain gauge (sometimes referred to as a strain gage) is a sensor whose resistance varies with applied force; It converts force, pressure, tension, weight, etc., into a change in electrical resistance which can then be measured. When external forces are applied to a stationary object, stress and strain are the result. Stress is defined as the object’s internal resisting forces, and strain is defined as the displacement and deformation that occur.

Code Example#

Use the three backticks to separate code.

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

Third Trial#

Usign the same circuit but adapting it into a glove and using some neopixels. So everytime you push your finger agianst the table it the neopixels will turn on since the gauge chages its resistance

Circuit integration#
