There are things which humans cannot hear, see, smell, or taste…. There is a whole universe out there, which we, cannot perceive using our own limited senses. This intriguing fact has spurred the invention of some of the most innovative sensors and devices, which allow us to “see” infrared, ultraviolet and other light waves beyond “visible” light, “hear” ultrasound, and radio waves, sensing objects that before, were unseen to us using Ultrasonic Sensors, Radar and other sensors. Using these devices and sensors, we can think about new ideas that go beyond our current knowledge and create new inventions!</span>


What is a Sensor? From Teach Engineering


List of Sensors: Wikipedia


Sight: A pixel will be worth a thousand words</span>

Recognition systems can pinpoint a face in a crowd. In the future, computer vision might save a life by analyzing patterns to make sense of visuals in the context of big data. In industries as varied as healthcare, retail and agriculture, a system could gather information and detect anomalies specific to the task—such as spotting a tiny area of diseased tissue in an MRI and applying it to the patient's medical history for faster, more accurate diagnosis and treatment.</span>

Hearing: Computers will hear what matters</span>

Before the tree fell in the forest, did anyone hear it? Sensors that pick up sound patterns and frequency changes will be able to predict weakness in a bridge before it buckles, the deeper meaning of your baby's cry or, yes, a tree breaking down internally before it falls. By analyzing verbal traits and including multi-sensory information, machine hearing and speech recognition could even be sensitive enough to advance dialogue across languages and cultures. </span>

Taste: Digital taste buds will help you eat smarter</span>

The challenge of providing food—whether it's for impoverished populations, people on restricted diets or picky kids—is in finding a way to meet both nutritional needs and personal preferences. In the works: a way to compute "perfect" meals using an algorithmic recipe of favorite flavors and optimal nutrition. No more need for substitute foods when you can have a personalized menu that satisfies both the calorie count and the palate.</span>

Smell: Computers will have a sense of smell</span>

When you call a friend to say how you're doing, your phone will know on the full story. Soon, sensors will detect and distinguish odors: a chemical, a biomarker, even molecules in the breath that affect personal health. The same smell technology, combined with deep learning systems, could troubleshoot operating-room hygiene, crops' soil conditions or a city's sanitation system before the human nose knows there's a p</span>
