Abstract: The present invention provides a battery safety test device includes: a mechanical switch element having one end connected to either a battery positive or negative electrode and the other end connected to an electronic switching element; the electronic switching element having one end connected to the mechanical switch element and the other end connected to the other of the battery positive or negative electrode; a voltage sensor for measuring a voltage of the battery after the mechanical switch element and the electronic switching element are turned on; and a current sensor for measuring a current of the battery after the mechanical switch element and the electronic switching element are turned on.

Abstract: An ultra-slim sensor device, comprising: a sensor element; lead wires (or lead frames) connected to the sensor element; a support for protecting the sensor element and the lead wires disposed therein; and upper and lower films disposed on upper and lower sides of the sensor element, the lead wires and the support to insulate them, wherein a thickness of the support is greater than that of the sensor element in order to protect the sensor element and the lead wires from external shocks, and the support gradually becomes thin toward the end thereof such that the upper and lower films come into contact with each other in order to remove a space between the upper and lower films.

Abstract: An ultra thin temperature sensor device includes a temperature sensor element, lead frames for allowing the temperature sensor element to be interposed and fastened between the lead frames, a supporter for protecting the temperature sensor element, and a film for enclosing and insulating the temperature sensor element, the lead frames, and the supporter. The supporter is formed to be larger than the temperature sensor element.

Abstract: A sensor element assembly, including: a sensor element; lead frames provided with the sensor element therebetween, the lead frames fixing the sensor element; a first head protection film protecting the sensor element fixed between the lead frames; an insulating film covering the first head protection film and the lead frames to insulate the lead frames; and a second head protection film (resin layer) further covering the head covered with the insulating film. The sensor element assembly is advantageous in that an epoxy resin layer is formed on a film layer covering a sensor element, so that the strength of the sensor element assembly can be maintained by the epoxy resin layer itself, thereby improving the impact resistance and compressive strength thereof.
