Abstract: A method for manufacturing a flex-tolerant three-dimensional printed antenna suitable for use in an electronic device provides a three-dimensional printed antenna with base layer, radiation layer, through holes, and feeder. The radiation layer includes a first radiation region, at least one second radiation region, and a feed end. A region between the first and second radiation regions is defined as a bent region. The radiation layer is formed by a screen-printing plate by a planar printing process. The through holes on the bent region form a line for bending. The feeder is electrically connected to the feed end. The second radiation region is canted from the bending line with respect to the first radiation region to form the three-dimensional printed antenna. The three-dimensional printed antenna and an electronic device are also disclosed.

Abstract: A method for manufacturing a bending-tolerant multilayered flexible circuit board (FPC) suitable for use in a disposable biosensor chip includes manufacturing and bending a single-sided FPC. The single-sided FPC includes a base layer, a wiring layer, and through holes. The wiring layer includes first and second wiring areas. A first bending area is formed between each first wiring area and the corresponding second wiring area, the through holes forming an easy bending line. The second wiring area is bent relative to the first wiring area along the bending line to obtain the multilayered FPC.

Abstract: An electrode which can measure a pH value of a buffer in an electrophoresis process and can realize an electrical connection between the electrophoresis detection device and a power supply is disclosed. The pH value of a buffer can range from 7 to 9. The electrode includes a metal. The metal wire is made of a conductive metal selected from a group consisting of titanium (Ti), platinum (Pt), titanium (Ti)/iridium (Ir) oxide, stainless steel, and any combination thereof. A pH measuring device including the electrode, and an electrophoresis detection system including the pH measuring device and an electrophoresis detection device are also disclosed. The electrode is made of metal wire, which has simple structure and good flexibility, being bendable according to actual need.
