Abstract
Embodiments of the present invention provide a method, system and computer program product for a biodegradable sensor device for mesh networking applications. In an embodiment of the invention, a biodegradable sensor device for mesh networking applications is provided. The device includes a frame formed of biodegradable material such as a mixture of polylactic acid and a resin, a biodegradable battery such as a flexible biodegradable lithium ion battery, an antenna, an environmental event detector formed from biodegradable material responsive to a change in environmental conditions, and signal generating circuitry configured to be responsive to detecting an environmental event by broadcasting a signal to other sensor devices in a mesh network and also to re-broadcast signals received from other sensor devices in the mesh network.
