The Tickle-Me Desk Lamp

Inspired by the Mimosa pudica, or shy plant, this lamp will feature petals that fold and close when not in use in order to safely and easily carry it around. Ideally, if I am able to use some kind of touch or motion sensor, then it will also be able to open and close its petals when touched, like the plant. The effect will be a lamp that is more of a companion, with feelings and emotions, than an inanimate source of light.

Scientific plant name: Mimosa pudica

Description: This plant is a creeping annual or perennial herb often grown for its curiosity value. The compound leaves fold inward and droop when toughed or shaken, to protect them from any predators. It is native to South and Central America. Like mentioned before, this plant is known for its rapid plant movement, meaning it undergoes changes in leaf orientation, called “sleep” or nyctinastic movement. The foliage closes at night, or when aggravated, and opens in the daytime. The response to any kind of disturbance, known as seismonastic movement, happens because certain cells lose turgor pressure, or the force applied to the cell walls by water. Once disturbed, parts of the stem are stimulated to release chemicals including potassium which force water out of the cell vacuoles, resulting in the closing of the leaflets and collapse of the leaf petiole.
