For example, paddle assembly 2042 is a piezoelectric generator formed by upper conductive layer 2044, piezoelectric material 2046, and lower conductive layer 2045. Thus, when paddle assembly 2042 absorbs energy from impacting molecules (or its own thermal vibrations in a vacuum), piezoelectric material 2046 will be stressed and a potential will be formed between upper conductive layer 2044 and lower conductive layer 2045. When this potential is connected to resistor assembly 2048, a current will flow through resistor assembly 2048. Heat is produced as a byproduct of current flowing through resistor assembly 2048. This heat can be captured by a thermoelectric generator or it can be used to heat a different substance. Thus, in accordance with the present invention, even infinitesimal voltages produced by the impacts of molecules 110 on paddles 100 can be used to heat resistive elements to useful values. This increased amount of force is directly proportional to the amount of stress induced upon piezoelectric layer 2046 of paddle assembly 2042. Thus, this increased amount of force will result in a higher potential being created in the piezoelectric generator.

In this manner, if the distance between switch 2091 and the resting location of paddle assembly 2042 is decreased then the number of times that lower conductive layer 2045 will come into contact with switch 2091 will, preferably, increase. Persons skilled in the art will appreciate that switch 2091 may be placed on either side of paddle 2042 depending on what polarity of power is desired. As shown in system 2700, this mounting assembly may include contact layer 2741, isolation layer 2752, and charge member layer 2722. However, system 2700 may also be configured, for example, such that only contact layer 2741 or isolation layer 2742 forms this mounting assembly. Dolor de hombro y cuello derecho . For example, nanotube 2711 may oscillate on average of about 10 meters per second at room temperature, even when transistor 2700 is operating in a vacuum. Persons skilled in the art will appreciate that nanometer scale transistor 2700 may be beneficially manipulated by an external magnetic field.
Assembly 1000 is configured such that the net charge of nanotubes 1002 in the assembly is zero, with half of the tubes including positive charges and the other half including negative charges. Field E induces current “i” to flow that flows from one nanotube, down one rail, across the other nanotube, and up the other rail (which, while illustrated as a clockwise current, may be counterclockwise at some other point in time when the direction of the motion of the nanotubes changes, thereby producing AC current). Base voltage 2621 may also be set such that nanotube 2611 touches emitter contact 2642 when the relative velocity of the tip of nanotube 2611 exceeds a particular amount (e.g., the velocity of point 1804 from FIG. When no static charge is placed on base terminal 2622, switch 2611 moves between positions 2612 and 2613 due to its thermal vibrations and rarely (e.g., once per hour) touches emitter terminal 2642. If a static charge is placed on base terminal 2622 and switch 2611 gains positive charge by voltage source 2631, switch 2611 may connect to emitter terminal 2642 more frequently (e.g, once per millisecond).

As illustrated, nanotube 2711 is in a closed position such that nanotube 2711 electrically couples collector contact 2741 to emitter contact 2742. However, when nanotube 2711 is located at positions 2712 or 2713, nanotube 2711 is in an open position such that nanotube 2711 does not electrically couple collector contact 2741 to emitter contact 2742. Generally, nanotube 2711 is attracted to emitter contact 2742 when the voltage applied to collector contact 2741 and the voltage applied to charge member 2722 are of opposite polarities. Sense circuitry 2792 may be coupled to contact layer 2742 to sense electrical signals provided by nanotube 2711 as nanotube 2711 electrically couples with contact layer 2742. Sense circuitry 2792 may also include the functionality of sensing the rate of contact between nanotube 2711 and contact layer 2742 for a period of time by sensing the number of electrical impulses provided from nanotube 2711 to contact layer 2742 per unit of time.
Nanometer scale electromechanical systems constructed in accordance with the present invention may include a large number of nanometer-sized objects, such as paddles, impact masses, and/or tubes, that are placed in a liquid or gas. Another object of the present invention is to provide nanometer scale electromechanical systems that efficiently convert molecular-level heat energy into useful mechanical and/or electrical energy.
