Abstract:
The present invention, in one embodiment, provides a method of measuring pressure or temperature using a sensor including a sensor element composed of a plurality of carbon nanotubes. In one example, the resistance of the plurality of carbon nanotubes is measured in response to the application of temperature or pressure. The changes in resistance are then recorded and correlated to temperature or pressure. In one embodiment, the present invention provides for independent measurement of pressure or temperature using the sensors disclosed herein.
Abstract:
The force-transmitting mechanism (400) includes a parallel-motion guide mechanism with a movable parallel leg (440), a stationary parallel leg, and at least two parallel-guiding members (450), wherein the parallel legs and the parallel-guiding members are connected to each other by flexure pivots and the movable parallel leg is constrained to the stationary parallel leg in guided mobility by the parallel-guiding members. The force-transmitting mechanism further includes a force-transmitting lever (480) which is pivotally supported on a fulcrum pivot (490) arranged on the stationary parallel leg, with a first lever arm (481) having a force-transmitting connection to the movable parallel leg by way of a coupling member (470), and a second lever arm (482) to which a measurement transducer (410) can be attached through a force-transmitting connection. The second lever arm includes a first partial lever arm (482A) and a second partial lever arm (482B), wherein the first partial lever arm is designed to receive the compensation force generated by the measurement transducer, and the second partial lever arm is designed for the detection of a displacement of the pivotally supported force-transmitting lever relative to a null reference of a position sensor (420).

A catheter assembly for assessing contact between the catheter assembly and tissue is disclosed. The assembly includes a catheter shaft and a pressure sensitive conductive composite member whose electrical resistance varies with pressure applied to the catheter assembly. The assembly also includes at least one measurement terminal to permit the measurement of changes in the electrical characteristics of the pressure sensitive conductive composite member. The assembly may optionally include a measurement device to measure resistance, impedance and/or other electrical characteristics. The assembly may utilize a reference electrode secured to the patient's tissue, which permits the measurement device to measure changes between the reference electrode and the at least one measurement terminal. Optionally, the assembly may include a conductive outer layer. Also disclosed are sensor assemblies, contact sensor, methods of contact sensing, and methods of manufacturing relating to the use of pressure sensitive conductive composites.
Abstract:
A load sensor includes: a substrate; a rib on the substrate; and two vertical transistors. Each vertical transistor includes: a gate electrode, a gate insulation film, and a semiconductor thin film on the side surface of the rib; a bottom electrode layer on a bottom of the substrate, on which the rib is not arranged, with contacting the semiconductor thin film; and a top electrode layer on a top of the rib with contacting the semiconductor thin film. Each vertical transistor flows current between the bottom electrode layer and the top electrode layer when a channel region is provided in the semiconductor thin film. Each straight line along normal line directions of the channel regions in the vertical transistors is arranged on a different side surface of the rib from each other, and has a predetermined angle between the straight lines.
Abstract:
A support apparatus includes a force sensing array positioned thereon that includes multiple layers of material that are arranged to define an elastically stretchable sensing sheet. The sensing sheet may be placed underneath a patient to detect interface forces or pressures between the patient and the support structure that the patient is positioned on. The force sensing array includes a plurality of force sensors. The force sensors are defined where a row conductor and a column conductor approach each other on opposite sides of a force sensing material, such as a piezoresistive material. In order to reduce electrical cross talk between the plurality of sensors, a semiconductive material is included adjacent the force sensing material to create a PN junction with the force sensing material. This PN junction acts as a diode, limiting current flow to essentially one direction, which, in turn, reduces cross talk between the multiple sensors.
