Clothes that change color based on your mood

Responsive Clothing

You’ve chosen to imagine clothes that change color along with your mood. You might want to learn more about responsive clothing that reacts to body signals. But be careful with your mood clothes; they make it a lot harder to hide your true feelings!

Fun Facts:

Mood rings became a huge fad in 1975, but their crystals actually changed color with body temperature—not emotions.
UC Berkeley researchers created Ripple shirts with stripes that change color when skin sensors notice excitement.
The experimental EmotiWear hoodie has special fibers that sense body signals and produce changing colored light.

Responsive Clothing

LISTEN

This scenario explores responsive clothing, which reacts to signals from our bodies. Some fabrics change with heat, while newer clothes sometimes use body sensors. These signals can give us clues about someone’s physical state, but they cannot read our minds. We should also choose when our clothes collect or share clues about our bodies. So be careful with your mood clothes; they make it a lot harder to hide your true feelings!

Fun Facts:

In 1975, mood rings used tiny liquid crystals that changed color as a finger became warmer or cooler.
Hypercolor shirts became popular in the early 1990s because their special pigments changed color with heat.
Ripple is a research shirt whose pattern changes color when a sensor detects changes in skin conductance linked with excitement.
Microsoft Research created Project Brookdale so designers can add sensors and other smart technology to clothing prototypes.
In 2026, researchers reported an experimental smart hoodie called EmotiWear that senses several body signals and uses glowing fibers for color feedback.

Discussion Question:

If clothes could collect and show clues about our feelings, how do we decide when others see them?

Physical Build:

You can design your own mood-changing shirt with paper, markers, and colored sticky notes. Draw a shirt, then create removable color patches for different body clues, like feeling warm or having a fast heartbeat. Decide which clues your shirt shares and which ones stay private.

Digital Build:

With an adult, ask ChatGPT:

“Design a shirt that can change colors using clues from my body.”

Then choose which signals your invention should notice. Draw your design and add a privacy button that lets you control what your clothes show.

or shoes that let you jump really high?

Super Jump Shoes

Wearable Exoskeletons

LISTEN

You’ve chosen to imagine shoes that give your legs an extra boost for giant jumps. You might want to learn more about wearable exoskeletons that help our bodies move. Just remember: super jumps belong on the playground, not over the lunch line!

Fun Facts:

In 1881, George Herrington patented spring stilts designed to help people leap higher and farther.
MIT researchers built springy leg exoskeletons that made repeated hopping use less energy in experiments.
In 2022, researchers tested a spring-powered knee exoskeleton that increased average jump height by 6.4% after users learned how to use it.

Wearable Exoskeletons

LISTEN

This scenario explores wearable exoskeletons, gear that works alongside our muscles. Some use springs that store energy when our legs bend. Others use motors to give our ankles an extra push. Researchers study them for walking, running, hopping, and jumping. Future shoes might use similar ideas to give our jumps extra bounce. Just remember: super jumps belong on the playground, not over the lunch line!

Fun Facts:

George Herrington’s 1881 spring-stilt patent described adjustable springs for leaping, walking, and running.
In 2009, MIT researchers tested fiberglass spring exoskeletons while people hopped repeatedly. One design lowered the energy their bodies needed for hopping.
A 2022 experiment used springs beside the thigh muscles to help people jump. After practice, participants jumped 6.4% higher on average.
Stanford built a robotic boot that gives the ankle an extra push while walking. Test users walked 9% faster while using less energy per distance.
Vanderbilt engineers created the Indego exoskeleton to help some people with spinal cord injuries stand and walk. It works like a wearable robot, with motors helping move the knees and hips.

Discussion Question:

If special gear could make us jump higher, when would using it be fair?

LISTEN

Physical Build:

You can prototype super jump shoes without actually jumping in them. Trace a shoe on cardboard, then add springs, folded cardboard, rubber bands, or craft sticks underneath. Test different pretend spring shapes by pressing them gently with your hand. Which design squishes and springs back best?

Digital Build:

With an adult, ask ChatGPT:

“Design safe future shoes that help people jump higher using spring-powered exoskeletons.”

Then choose your favorite feature and draw the shoes from the side. Label where they store energy, support your legs, and help you land safely.
