Disposable Chemical Sensor and Wireless Communication Device

A disposable chemical sensor and temperature device has been developed that may be dropped into building rubble or other areas not accessible by rescue personnel to test the environment in the rubble. The system also provides wireless two-way communication and control to obtain information concerning the environment prior to disturbing an area under the rubble, and gives an indication of the likelihood that the area is a candidate for finding survivors. In addition, it would provide two-way communication between a survivor trapped in the rubble and a surface rescue worker, such that a survivor can be alerted to the fact that he or she should make a sound to make his or her presence known.
