Do you wear a watch or a fitness tracker? Those are the gadgets that tell us what time to get up or how much exercise to do. Have you seen a robot walking past you? There are always so many cool gadgets that surround us: watches, fitness trackers, robots. They all have something in common. They have things called sensors. Center for Sensorimotor Neural Engineering explains that the sensor is a device that gives the system a signal for certain stimuli. A popular sensor is Flex Sensor 4.5 Inch; it can give a signal when it’s been bent or stretched. Simply put, it’s a magic eye that perceives the changes in things. What is Wearable Technology? As we all know, wearable technology has already existed for a long time. Fifty years ago, the first-ever wearable device was invented – a calculator watch. Today, wearable technologies are more diverse. In addition to the fact that the fitness tracker counts the steps taken, the smartwatches displays messages, and the special clothes are following our moves. How do wearable devices know when to move our arms or legs or head? Sensors are small “brains”. The Flex Sensor 4.5 Inch has a similar sensor, but it can perceive the minimum changes in the form. Such a sensor is good because it’s small, 4.5 inches long, and ideal for wearable technology: due to its smallness, it can be folded into small gadgets. For example, how would you like to wear a big, clunky watch?
The Flex Sensor 4.5 Inch has many usages, which is another excellent thing about it. And it is in medical devices, used to help doctors control patients — or robots that assist with certain tasks. It is good for highly precise fields such as medical or manufacturing, where a small change in shape and movement should be detected.
That being said, how does the Flex Sensor 4.5 Inch actually operate? The stretch sensor — a bendy strip with an internal resistor. The resistor acts like a gate of sorts, to allow current. As the strip bends or moves changes its shape, change on resistance. If the strip is straight, that means it has high resistance — so electricity does not flow through. But when it flexes, the resistance decreases so that more electricity can flow. This resistance changes with how much the strip is being bent or deformed by. Its like a measuring stick for how things have become different from what they were!
Robots really are the coolest machines! They can perform a wide variety of tasks, from putting together cars on an assembly line to assisting with surgeries. As great as it is for that, if we want to have our robots adequately move and perform their intended tasks well then precision movement control of the robot becomes really important.
That is where the Flex Sensor 4.5 Inch comes in! For example, one can put this sensor into the joints of hydraulic robots actuated by a fluid or somewhere in the limbs so that robot should feel how force it applies to an object. This means the robot can feel how much it is bending or moving. Consequently, it can then adjust its behavior appropriately — which means smoother and more accurate movements. Moving a task-activating SELECT/STORE from off the chip to on-chip is critical for applications such as surgery where accuracy (less jitter) counts or in multiple robots working together safely and not running into each other, etc.
Flex Sensor 4.5 Inch also a great tool for DIY project This sensor might be kind of helpful, if you are interested in making your own electronics or a robot. It can be used in conjunction with other parts such as microcontrollers (your devices' brains) and motors to make them move. Combine these parts to make cool wearable devices that react and move according to the shape..
e.g. you could create a smart glove which is capable of figuring out how your hand moves and with that information control an robotic arm That would be so much fun! Iff it's a bad posture, e.g create a wearable device that tracks your postion and reminds you when to maintain yourself upright. The Flex Sensor 4.5 Inch has a wide range of potential applications!
