Solution-processed negative temperature coefficient (NTC) thermistor devices include transition metal dichalcogenide (TMDC) quantum dots. The TMDC quantum dots may be formulated into an ink, and the ink may subsequently be deposited on a substrate and processed to form an NTC thermistor. Solution-processed NTC thermistors may be incorporated into RFID tags or as circuit protectors into electronic circuits.

A medical temperature monitoring system includes an electrical wire set having a thermistor at a distal end of the wire set configured to sense temperatures to which the thermistor is exposed; an electronic circuit in electrical communication with the wire set and the thermistor and configured to convert the temperatures sensed by the thermistor to temperature display signals; a display in electrical communication with the electronic circuit for receiving the temperature display signals and displaying temperatures corresponding to the temperature display signals; and a bead of cured protective material encapsulating the thermistor. The protective material is a radiation curable adhesive applied to the thermistor in an uncured state and then cured to encapsulate the thermistor. The bead of cured protective material electrically isolates the conductor sufficient to pass a Hi-Pot test at 500 VAC, <0.1 mA.

A multi-terminal surge arrester which includes an active part extending along a longitudinal direction of the surge arrester, a first electrode resting against a first end of the active part, and a second electrode resting against a second end of the active part, which second end opposes the first end in the longitudinal direction of the surge arrester. The surge arrester further includes an insulating fixing device mechanically connecting and fixing the first electrode and the second electrode, and an insulating housing arranged around the active part. The active part includes at least two metal-oxide based varistor elements and a further electrode arranged between the at least two varistor elements, which further electrode provides an externally accessible electrical connection. Therein, the surge arrester is adapted for being insulated by surrounding air.

A sliding variable resistor includes a sliding base, a first supporting pole, two buffering members, a substrate, a casing assembly, an anchoring plate, a driving member, a driven member, a belt, and a belt guard. The sliding base includes two first through hole and at least one variable resistor sheet. The first supporting pole is inserted into the two first through hole. The first supporting pole has its two ends abut against the first buffering seats, respectively. The substrate is engaged with the two buffering members. The two buffering members are arranged in the casing assembly. The anchoring plate is fixedly arranged on the casing assembly. The belt is engaged with the driving member and the driven member, respectively. The belt guard is fastened to the sliding base, and is engaged with the belt. As such, the sliding base, while sliding, can have an improved smoothness.

A surge arrester has a resistance column which is pressed together by one or more clamping devices. The clamping devices are each fixed at both ends of the resistance column to an end fitting by way of a fixing device. An electrically insulating housing encloses the fixing device. Each end fitting has a first contour, on which the fixing devices are arranged and which is enclosed by the housing. The end fitting also has a second contour with a smaller diameter than the first contour.
