A flexible conductive element (1) comprising at least one insulating layer (2) and at least one conductive track (4) fixed to the at least one insulating layer (2), wherein the conductive track (4) has a plurality of stretches (3), and wherein the adjacent stretches of said plurality of stretches (3) have a different orientation one another, and wherein said insulating layer (2) is made of a thermoplastic polymeric material; wherein said adjacent stretches (3) are joined with a radius of curvature greater than 0.5 mm.

An ion detection assembly is described that includes a drift chamber, an inlet assembly, and a collector assembly. The drift chamber is formed of substantially non- conductive material and / or semi-conductive material. A patterned resistive trace is deposited on one or more of an interior surface or an exterior surface of the drift chamber. The patterned resistive trace is configured to connect to a source of electrical energy. The inlet assembly and the collector assembly are in fluid communication with the drift chamber. The inlet assembly includes an inlet for receiving a sample, a reaction region for ionizing the sample, and a gate for controlling entrance of the ionized sample to the drift chamber. The collector assembly includes a collector plate for collecting the ionized sample after the ionized sample passes through the drift chamber.

This utility model relates to a thick-film heating plate resistor structure and a heating plate. The heating plate resistor structure comprises multiple layers of resistors 1 with different arc lengths distributed along the radial direction and interconnected to form a disk-shaped distribution. The resistors 1 are divided into heating zones a, b, c, d, e, f, g, and h with the center of the disk as the center. The resistors 1 include a first resistor segment 2 covering the heating zones a, b, c, d, e, f, g, and h. The first resistor segment 2 is connected to a second resistor segment 3, which is distributed along the radial direction with unequal arc lengths to cover the heating zones a, b, c, d, e, f, g, and h. The second resistor segment 3 is connected to a third resistor segment 4 and a fourth resistor segment 5, which are symmetrically arranged along the radial direction of the center of the disk. By placing the first and third connecting ends in the e and f regions, and by reducing the width of the lines and decreasing the amount of S in the a and b regions to increase functionality, and by increasing the width of the resistor lines S and shortening the length of the resistor lines L in the e and f regions to reduce power, the heat effect can be more rationally distributed and the phenomenon of scorching can be reduced.
