-======= Miniature Pressure Transducer ======= 
  
-===== Summary ===== 
-==== Introduction ==== 
-The **miniature pressure transducer** or **MPT** is cleverly designed to minimize sensor size while maintaining usable bandwidth. ​ A foil [[strain gauge]] is coupled to a flat support plate, which is then mounted to the edges of a dome-like cover. ​ When pressure is applied to the MPT, the support plate deforms, elongating the strain gauge (Burdea 1996). 
- 
-==== Types of MPT ==== 
-While [[force-sensitive resistor|FSRs]] come in packages with a diameter as small as 7.1 mm, the necessity of a tail that is relatively fragile and bulky limits their usefulness when volume intrusion must be minimized. ​ Precision Measurement currently manufactures two sizes of MPT that may be suitable for musical applications. ​ One has a diameter of 2.7 mm and is 0.5 mm thick. ​ The other has 1.5 mm diameter and is 0.3 mm thick. ​ Thus these sensors may also be able to be integrated into acoustic instruments for measurement or control augmentation with relatively little effect on normal playing. 
- 
-==== Output ==== 
-Because the MPT is based on the output of a strain gauge, it should be connected to a [[Wheatstone bridge]] circuit. ​ The deformation of the gauge causes an increase in electrical resistance, which can be measured as a voltage by an [[operational amplifier]] (Burdea 1996).
