Wireless remote data
Technologies and sample systems that gather sensor data across distances, usually via radio links. This includes general telemetry and SCADA (supervisory control and data acquisition), especially for gathering data about wildlife, natural resources, and distributed energy systems.

Self-Assembling Batteries:  "Researchers at MIT have designed a rechargeable lithium-ion battery that assembles itself out of microscopic materials. This could lead to ultrasmall power sources for sensors and micromachines the size of the head of a pin. It could also make it possible to pack battery materials in unused space inside electronic devices."  Earlier related story:  Batteries That Assemble Themselves: "Biology may be the key to producing light-weight, inexpensive, and high-performance batteries that could transform military uniforms into power sources and, eventually, improve electric and hybrid vehicles. Angela Belcher, an MIT professor of biological engineering and materials science, and two colleagues, materials science professor Yet-Ming Chiang and chemical engineering professor Paula Hammond, have engineered viruses to assemble battery components that can store three times as much energy as traditional materials by packing highly ordered materials into a very small space."  3:08:44 PM  permalink  

Researchers convert heat to electricity using organic molecules:  "Arun Majumdar, UC Berkeley professor of mechanical engineering was principal investigator of the study..  [His team] successfully generated electricity from heat by trapping organic molecules between metal nanoparticles, an achievement that could pave the way toward the development of a new source for energy."  While it's a long way from marketable form, it would have implications for energy, nanomaterials, and sensors (which need small amounts of energy to function).
