♦ What is Force Sensing Resistor (FSR)?

Force sensing resistor or we call force sensor, can be defined as a special type of resistor which exhibits a decrease in resistance with an increase in the force applied to the active sensing surface. The force sensing resistor is generally supplied as a polymer sheet or ink which is applied as screen printing. Both the electrically conducting and non-conducting particles are present on this sensing film. If force is applied to a surface of sensing film, then the particles touches the conducting electrodes and thus resistance of the film changes. There are several resistive based sensors but force sensing resistors operate satisfactorily in difficult environments and also requires a simple interface compared to other resistive based sensors.
Even though there are various types of force sensors , the force sensing resistors are having several advantages such as thin size (less than 0.5mm), very low cost and also good shock resistance. The only disadvantage of FSR sensors is low precision, there will be approximately 10% or more difference in measurement results. So it can’t be used as weighing equipment. It acts as a reaction of force rather than as an accurate reading of pressure.

♦Applications of Force Sensing Resistor

There are numerous applications for force sensing resistors in various fields such as motion analysis systems, automobiles like car sensors, resistive touch-pads, musical instruments, Medical bed, Measurement of bite force of teeth, die pressure measurement,and so on. It may be used wherever pressure measurements and data collection are required.

1. How to make an order?
Please tell us your material,artwork design,logic circuit principle chart,size,surface,usage etc. And better send us the design drawing or samples together with other detailed datas, then we’ll customize the membrane switch upon your requests.
2. Sample available?
Yes, but based on freight collect. Most of the items are customized for clients, so molding charge is needed.
3. How to guarantee the after sales service?
We will track the production situation of the goods during the whole process,we promise the goods will be shipped to you smoothly. If any problem happened, we will provide the best solution for you.
4. Shipping ways & Delivery Time?
Shipping by: UPS/ Fedex /DHL /TNT or other ways specified.
Delivery time: 15~20 days after payment received.
5. Payment terms: 100% T/T in advance.
