Heart Signal

A Creative Hoodie for Shy Single Men and Women

This project is targeting to design something wearable based on an emerging or established piece of technology, so students need to learn how the technology works, then design and make something inspired by this technology. This project can take the form of a prototype or proposal, but in either case, it must include some real-life technical experimentation.

DESIGN PROCESS

BRAINSTORMING

The technology I chose: Motion Sensor Lighted Magnifying Mirror

RESEARCH 1: HOW TO MAKE A MOTION SENSOR LIGHTED MAGNIFYING MIRROR

Intelligent multi-sense

The sensor of the mirror has multi-sense technology that adapts to your behavior. It automatically lights up as your face approaches the mirror. During use, it becomes more sensitive so it won't turn off unexpectedly. When you're finished, it shuts off automatically – very efficient.

Passive infrared sensor (PIR sensor)

The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens used here is not really doing much and so we see that the two slots can 'see' out past some distance (basically the sensitivity of the sensor). When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When a warm body like a human or animal passes by, it first intercepts one half of the PIR sensor, which causes a positive differential change between the two halves. When the warm body leaves the sensing area, the reverse happens, whereby the sensor generates a negative differential change. These change pulses are what is detected.

IMITATING EXISTING TECHNOLOGY

I imitated the Motion Sensor Lighted Magnifying Mirror by using Arduino.

Components I used: Vanity Mirror, Arduino, PIR Sensor (Motion Sensor), LED Strips, Battery pack

PROJECT STATEMENT

I got inspiration from the motion sensor mirror, and decided to make a Heart Signal Hoodie. I would like to using sensor to track heart beats, and when the heart beats goes faster, the hoodie would lighting up.

When a man see a woman and feels like her, his heartbeat would goes faster, and his clothes would lighting up and tell the woman he likes her. Vice versa.

RESEARCH2: WHAT SENSOR I NEED FOR THE HEART SIGNAL PROJECT?

Pulse Sensor

Pulse Sensor Amped is a plug-and-play heart-rate sensor for Arduino and Arduino compatibles. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects. Pulse Sensor adds amplification and noise cancellation circuitry to the hardware. It's noticeably faster and easier to get reliable pulse readings. Pulse Sensor Amped works with either a 3V or 5V Arduino.

PROTOTYPE

I use LED strip to make all the letters (CALL ME & the phone number), and then soldering the different part one by one. I also made a heart shape LED lighting board. By linking the Arduino and pulse sensor to the hoodie, the LED letter and the heart will lighting up when the heart beats data higher than 500 (scale from 0-1000).
