Provided is a cantilever that is capable of bending and deforming in an active manner by itself. The cantilever includes: a lever portion having a proximal end that is supported by a main body part; and a resistor member that is formed in the cantilever and generates heat when a voltage is applied, to thereby deform the lever portion by thermal expansion due to the heat.
摘要:
The sensor has the self-detecting probe including a body portion, an elongated belt-like flexible substrate, connecting members, a resinous portion, and external contacts formed at the ends of the flexible substrate brought out of liquid. The probe further includes a cantilever whose base end is supported to the body portion, a strain resistive element whose resistance value varies according to the amount of displacement of the cantilever, and interconnects electrically connected with the strain resistive element. A probe tip is formed at the front end of the cantilever. The flexible substrate has an interconnect pattern sandwiched between two insulating sheets. The flexible substrate supports the body portion while the cantilever protrudes outwardly. At least one end of the flexible substrate is brought out of liquid. The connecting members connect the interconnects with the interconnect pattern. The interconnects, connecting members, and the portions of the connecting members electrically connected with the interconnect pattern are coated with the resinous portion.

A cantilever has a probe portion and a cantilever portion having a free end portion from which the probe portion extends. A displacement detecting portion detects a displacement of the cantilever portion according to an interaction between a sample and the probe portion. An electrode portion is connected to the displacement detecting portion. An insulation film is formed over at least one of the electrode portion and the displacement detecting portion. A functional coating in the form one of a conductive film, a magnetic film, and a film having a light intensity amplifying effect is disposed on the insulation film.

A scanning probe microscope having a cantilever holder is provided which gives a cantilever great amplitude by a small-sized vibrator configurable in a limited space and is stably operated even in environments of high viscous drag such as a liquid. A cantilever base part of a cantilever is fixed to a fixing part of a scanning probe microscopy cantilever holder. A vibrator is mounted on the fixing part. When it is defined that the front side is the side close to a probe and the rear side is the side close to a supporting part of the fixing part along in the longitudinal direction of the cantilever, the vibrator displaces the front and rear sides of the fixing part of the cantilever holder to each other in the opposite directions within the plane orthogonal to the sample surface to vibrate the cantilever in a liquid.
