"Electronic bandage speeds wound healing and dissolves into body after use"

"Electronic bandages are an emerging but by no means new technology, with earlier developments into bacteria-killing patches, motion-powered covers and even forays into smart dressings. But this dressing is the first bioresorbable bandage of its kind, delivering electrotherapy to wounds to accelerate healing by up to 30 per cent, and relaying data on the injured site's condition to allow monitor of it from afar. The Northwestern scientists believe it could be a game-changer for diabetics and others who face serious complications from frequent and slow-healing sores. Although it’s an electronic device, the active components that interface with the wound bed are entirely resorbable,” said Northwestern University’s John A. Rogers, who co-led the study. “As such, the materials disappear naturally after the healing process is complete, thereby avoiding any damage to the tissue that could otherwise be caused by physical extraction."

Ideation and Intention

Having researched into electronic bandages, I knew I wanted to make something that would help the human body. My personal experience around sleep is what motivates this project. I have a very fragile sleep. I need to shower, wear a sleeping mask, take supplements for deep sleep and use essential oils to feel fresh and comfy.

Research on sleep and ElectroMagneticFields or EMF

The premise of the project is this:

Conclusions "Sleeping in a bed that isolates from EMFs and drain them can be a possible strategy to improve the secretion of hormones related to a better response to stress and sleep quality, which means a better endocrine system, and consequently better homeostasis and maintenance of health. This fact was confirmed with the slowdown in the rate of aging checked with a rejuvenation of the biological age." Read full article here

Arduino and ElectroMagneticFields Sensor or EMF Sensor

This one is super cool because it uses light to demonstrate the level of exposure:



int inPin = 3; 
int var = 0;
int pin11 = 5;

void setup() {
void loop() {
  var = analogRead(inPin);
  if(var >= 1)
    var = constrain(var, 1, 100;                        
    var = map(var, 1, 100, 1, 255);
    analogWrite(pin11, var);
  analogWrite(pin11, 0);

Process and workflow

For this assignment I will use the MAGNETIC SPRING SENSOR instead because this is the one I have available at the Basque Design Center. Essentially, it´ll be used to demonstrate the concept.


Use the three backticks to separate code.

int led = 13; // define the LED pin
int digitalPin = 3; // KY-025 digital interface
int analogPin = A0; // KY-025 analog interface
int digitalVal; // digital readings
int analogVal; //analog readings
void setup()
  pinMode(led, OUTPUT);
  pinMode(digitalPin, INPUT);
  //pinMode(analogPin, OUTPUT);
void loop()
  // Read the digital interface
  digitalVal = digitalRead(digitalPin); 
  if(digitalVal == HIGH) // if magnetic field is detected
    digitalWrite(led, HIGH); // turn ON Arduino's LED
    digitalWrite(led, LOW); // turn OFF Arduino's LED
  // Read the analog interface
  analogVal = analogRead(analogPin); 
  Serial.println(analogVal); // print analog value to serial
