New tech that senses how you're feeling inside: is it the key to self-knowledge and the future of communication? Or just the return of the phony "mood ring"? Check out our gallery of the top mood-sensing technology in development.

Sensoree have coined a new word to explain why they invented the "Mood Sweater." It's all about extimacy -- that's "externalized intimacy," apparently. Two sensors on the wearer's palms measure changes in electrical conductance, and a light collar glows in different hues to communicate their emotional state. Sensoree sound pretty confident in their design: the sweater even "replaces speaking," they say, "as the wearer's truths are instantly expressed with color." Pre-order it now and you'll never have to speak again!

This concept dress called Bubelle by Philip's Design interacts with and predicts the wearer's emotional state by changing colors. A beautiful white can turn into a relaxed blue. Philip's dresses are made from high-tech materials and are still in the concept phase.

Dutch design collective Studio Roosegaarde have developed a sensual dress called Intimacy 2.0 together with designer Anouk Wipprecht. Made of leather and smart e-foils, it 'explores the relationship between technology and intimacy'. The high-tech panels are stimulated by the heartbeat of the wearer. Initially opaque or white, they become increasingly transparent when exposed to an electric current -- in this case a beating heart.

Ever wonder if someone is flirting with you? With the Blinklifier you wont. The device -- created by designers Tricia Flanagan and Katia Vega -- monitors eye muscle contractions using fake eyelashes. It sends these signals to an array of lights housed in a piece of headwear (via lines of conductive eyeliner) and can turn every wink or batted eyelash into an elaborate light-show. Or make you look like an illuminated Christmas tree...

The world was amazed and offended (and slightly creeped-out) when Microsoft announced a bra that tracks a woman's emotional state to combat overeating. The smart bra sends a signal to the wearer's smartphone when it identifies a trigger for binge eating, such as discomfort or stress. Microsoft say it wont be coming out any time soon.

Feeling healthy? Have a tattoo tell you whether it's all going well on the inside. That is the idea behind UC San Diego's Biosensor Tattoo: the tiny temporary tattoo monitors the pH levels and lactate content in a wearer's sweat to assess the metabolic health of a patient. It's supposed to help athletes know if they're overdoing it, and whether their stamina is improving with exercise. But will it come in sailing anchor and "I (heart) mum" versions?
