The Morphix Chameleon is a portable chemical detection device. It consists of a reusable armband, wearable over many hazardous-material suits, on which removable sensors are mounted. The sensors have color-changing tags that indicate the presence of hazardous or dangerous chemicals in the air, allowing personnel in the field to make decisions about dangerous situations.

Development
The Chameleon was developed by Morphix Technologies during the early 2000s. Morphix Technologies won a Small Business Development and Research grant in 2002 to design a device that could indicate the presence of dangerous gasses or vapors cheaply, easily, and quickly. The design for the armband came from requests from military who needed it to be unobtrusive, while the replaceable sensor part (cassette) came from a need to keep it affordable for police and emergency responders.
Benefits
The Chameleon can be used in high temperatures, arctic cold, in the desert, or even after being submerged in water, and still detect up to one-part-per billion of dangerous air-borne hazards. After opening the sensors, they have a 24-hour life-time before function begins to be hampered. Compared to complicated chemical detection devices that are in the price range of thousands or tens of thousands of dollars, the Chameleon costs thirty U.S. dollars for the armband and three U.S. dollars for each sensor.
The armband
The Chameleon’s lightweight and unobtrusive armband has room for ten of the eleven sensor cassettes that are currently produced, and can easily swap out used sensors for quick replacements. It was designed with military and emergency situations in mind, and can be easily put on or taken off, with enough adjustment to be able to fit easily over even the highest level of hazardous material protective gear.
The sensors
The sensors function similarly to litmus paper. The cassettes that hold the sensors are mounted onto the armband, and can be easily removed. The cassettes have a small viewing window which shows a uniform colored surface when not exposed to its particular trigger. Once exposed to it, half of the viewing window will change color, presenting a contrast that allows users to recognize that a threat is present. The sensors detect acidic and basic gases, ammonia, chlorine/fluorine, diborane, hydrazine, hydrogen sulfide, iodine, phosgene, phosphine, and sulfur dioxide. After opening, they retain functionality for up to twenty-four hours. The sensors come packaged in groups that allow them to be easily changed out depending on the scenario. These groups are Chemical Suicide, Clan-Meth Lab, or Haz-Mat detection, which are the most common configurations used.
Uses
In addition to being worn directly, the idea exists of mounting the Chameleon onto Aerial Drones or Ground Drones to further extend its utility in certain situations.
Military, police, and emergency crews all report benefits from use of the Chameleon. It won the 2007 Innovation Awards from Law Enforcement Product News in the category of “Haz-mat/WMD”.
