Image sensors are instruments used for converting optical images into electronic signals. The global image sensors market has grown immensely due to technological advancements in the last decade. This has stimulated diversification in image sensor applications. Image sensors have been placed on board NASA’s Interface Region Imaging Spectrograph (IRIS) spacecraft to capture the first images of the Sun.
Ultrasonics is defined as vibrations of frequencies greater than the upper limit of the audible range for the human ear.
Laser triangulation sensors determine the position of a target by measuring the reflected light from the target surface. Based on their intended application and performance, these sensors can be classified into two categories.
MTI Instruments, a company specializing in non-contact measurement solutions, offers the Accumeasure capacitance-based systems that are specifically designed to perform noncontact measurements of runout, position, vibration, and displacement.
Nicéphore Niépce is widely attributed as being the inventor of photography, but he may not have envisioned how far camera technology would advance. Printable image sensors are one such development that has offered manufacturers huge benefits in flexibility, scalability and cost.

Steven LeBoeuf, President of Valencell Inc., talks to AZoSensors about the development of PerformTek, an accurate wearable biometric sensor.
Cynophobics may soon be able to avoid the anxiety of being sniffed by the canine police at airports thanks to the development of a nanosensor by a team of researchers at the University of California, Berkeley. The new technology, which uses light based plasmon sensors, can identify the smallest and most difficult to detect explosives and so could be employed at airport security in the near future.

Resistors, thermocouples, and diodes are the commonly used temperature sensors for cryogenic applications.
The world’s population is rapidly expanding with a huge proportion of this growth found in our cities. The increased population and our modern life style are putting more pressure on the infrastructure within our cities. Researchers are now using sensor technology with the aim of making our cities more efficient.

It is uncommon to meet somebody in the developed world who doesn't own a cell phone these days, in fact there are almost as many cell phones in the world as humans. Smartphones, with the capability of internet access and built in applications, have become a useful tool to track information about the user. This information can include health, travel and hobbies and can give a fairly accurate representation of the personality of its owner.
