What are force sensitive resistors used for?
Sensitronics is the leader of The Force-Sensing Resistor (FSR) technology. Force Sensing Resistors can be used for such applications as computer input devices, musical instruments, medical instruments, robotics, automotive, interactive toys, sports and more.
How accurate are force sensitive resistors?
These sensors are fairly low cost, and easy to use but they’re rarely accurate. They also vary some from sensor to sensor perhaps 10%. So basically when you use FSRs you should only expect to get ranges of response.
How do you test a force sensitive resistor?
The easiest way to determine how your FSR works is to connect a multimeter in resistance-measurement mode to the two tabs on your sensor and see how the resistance changes. Because the resistance changes a lot, a auto-ranging meter works well here.
How do you connect a force sensing resistor?
To do this you connect one end of the FSR to Power and the other to a pull-down resistor. Then the point between the fixed value pull-down resistor and the variable FSR resistor is connected to the ADC input of an Arduino.
What are force sensitive resistors made of?
How are Force Sensing Resistors Made? Force sensing resistors consist of a semi-conductive material – or, semi-conductive ink – contained between two thin substrates. As shown in Figure 2, there are two different types of force sensing resistor technologies – Shunt Mode, and Thru Mode.
What is a FlexiForce sensor?
FlexiForce™ sensors measure force between almost any two surfaces and are durable enough to stand up to most environments. FlexiForce sensors are ideal for integrating into OEM products because their thin, flexible profile allows them to measure forces where larger, bulkier technologies can not.
How does a FlexiForce sensor work?
The FlexiForce sensor acts as a force sensing resistor in an electrical circuit. When the force sensor is unloaded, its resistance is very high. When a force is applied to the sensor, there is a proportional decrease in resistance. measurement of higher loads than other force sensitive resistors.
Can you cut an FSR?
Answer: Yes – it is possible to trim the FlexiForce sensor if the sensing area is too large or the wrong shape for your application. However, please keep in mind that trimming the sensing area can result in less durability, potential for shorting, and less sensitivity.
Where are force sensors used?
Medical Applications – force sensors are used within the medical industry. They are used for fluid monitoring applications, dialysis machines, endoscopic surgery, physical therapy equipment, orthopaedics and MRI devices.
How many types of force sensors are there?
There are three main types: tensile force, compression force or tensile and compression force sensors. On top of that we provide force sensors with two or three measuring ranges as so-called multi-component sensors, or in a double bridge version (plausibility circuit).
Are force sensitive resistors waterproof?
WATERPROOF– Force sensor has pressure sensitive function as well as water-resistant function. It can work normally under the temperature from -20℃/-4℉ to 60℃/140℉.
