There is currently a strong movement worldwide toward portable, battery operated, wirelessly connected devices such as GPS receivers, cellular telephones and laptop computers and tablets. This new generation of electronics enables vast  new  capability,  but  also  comes  with  new  challenges  such  as  bandwidth  limitations,  sensitivity  to  jamming  and  reduced  access  to  calibration.  A  new  generation  of  miniature,  low-power,  low-cost  precision  instruments  is  being  developed  at  NIST  for  use  in  such  portable  technologies.  These  include  clocks, magnetometers, gyros and wavelength references, all based on precision atomic spectroscopy and using emerging new fabrication capabilities such as microelectromechanical systems and photonics. This talk will describe the design,  fabrication  and  performance  of  these  instruments,  as  well  as  touch  on  several applications to which they are well-suited. Finally, we will speculate on future opportunities for these types of devices such as compact instruments based on laser-cooled atoms and a broader view on highly accurate chip-scale measurements.
