Innovators at NASA's Johnson Space Center (JSC) have developed and patented a method and apparatus for a sensor-based miniature data acquisition system that receives, amplifies, and filters signals. The invention allows many instrument channels to be fabricated on a single chip without the need for external capacitors and without devoting excessive chip area to capacitors. NASA developed the technology to provide for remote operation of the human-like hand of its Robonaut, a prototype robotic astronaut assistant. The innovation uses continuous time operational amplifier circuits made from specialty analog complementary metal-oxide-semiconductor (CMOS) processors and two stages of instrumentation amplifier circuitry, resulting in higher gain and sensitivity. Overall, the design is simpler and less prone to noise than conventional systems. JSC has received patent number 6,943,621 for this technology.
