Solid-state sensors future trends

This field is in its infancy with the future open to growth in new directions. The geometric dimensions of electronic devices and molecular assemblies are moving closer together. As this trend continues it will be possible to prepare solid-state sensors for detection of small numbers of atoms, molecules, and ions in gases, liquids, and in some solids, as well as in living systems.

In contrast to forecasts of 10 years ago, biosensors with biochemical reagents fixed to a solid-state chip placed on an intravasal catheter have acquired no clinical significance so far. One reason in addition to the lack of availability is the trend towards less invasive methods. This opinion is based on the increased clinical use of more precise sensors to monitor gas exchange and metabolism. The future availability of faster and more precise mainstream sensors and the extended processing of smart systems will offer new non-invasive global parameters. This will include non-invasive monitoring of hemodynamic parameters such as cardiac output by means of saturation and oxygen consumption, or arteriovenous shunts.
