The thermistor is basically a two-terminal solid state thermally sensitive transducer constructed using sensitive semiconductor based metal oxides with metallised or sintered connecting leads formed into a ceramic disc or bead. This allows the thermistor to change its resistive value in proportion to small changes in ambient temperature Thermistors are mainly used as temperature sensors, inrush current limiters, self-resetting over-current protectors and self-regulating heating elements.

Doped semiconductor thermistors --- in particular, ones made from ion-implanted silicon and neutron transmutation doped (NTD) germanium --- were the first thermometers used in x-ray calorimeters. An advantage of using silicon is the existence of well-established micro-machining techniques for fabricating devices in which the active pixels and their links to the heat sink form a monolithic array A thermistor is made with a semiconductor and an insulator, where resistance could be found between the insulator and conductor. A sintered mixture of metallic oxides, such as iron, uranium, copper etc is typically chosen, along with an insulator coating the semiconductor. It is available in different forms as well
A thermistor is a temperature-measuring device that is based on the notion that the electrical resistivity changes with temperature. Thermistors are commonly semiconductors or metals. For metals, the resistivity increases with increasing temperature; for semiconductors, the resistivity decreases with increasing temperature.

NTC thermistors are temperature-dependent resistors that employ special semiconductor ceramics with a negative temperature coefficient (NTC). They have a high resistance at room temperature, and when they are energized, they generate heat by themselves and the resistance falls as their temperature rises
A thermistor is a type of resistor whose resistance varies significantly (more than in standard resistors) with temperature. The word is aportmanteau of thermal and resistor. Thermistors are widely used as inrush current limiters, temperature sens.. Virtually all semiconductors and the circuits comprised of them exhibit a temperature coefficient. Owing to their high positive temperature coefficient, NTC thermistors are particularly suitable for compensating this undesired response to temperature changes (examples: working point stabi As the Thermistor is made of semiconductor material, they have both the negative and positive temperature coefficient.But most of them thermistor have a negative temperature coefficient, i.e., their resistance decreases with the increases in temperature. The negative temperature coefficient can be large enough for several percentage increases in temperature because of the Thermistor can detect.

A thermistor is a semiconductor and its resistance drastically changes with temperature. Shibaura's thermistors cover a full range of temperatures from -50 to 1000℃ that require daily temperature control Thermistors are available in two types: PTC (positive temperature coefficient) and NTC (negative temperature coefficient). The resistance of a PTC thermistor increases as the temperature increases. In contrast, the resistance of an NTC thermistor decreases as temperature increases, and this type seems to be the most commonly used thermistor Both RTD and Thermistor are used to detect the change in temperature. However, the crucial difference between RTD and Thermistor lies in the material of their construction.RTD is constructed with materials that are pure metals whereas thermistors are fabricated with semiconductor materials of ceramic or polymers Thermistor Similar to the RTD, the thermistor is a temperature sensing device whose resistance changes with temperature. Thermistors, however, are made from semiconductor materials (figure 4).

Definition of Thermistor. The thermistor is the type of thermal resistor whose resistance changes with the temperature. It is made of semiconductor material. The thermistor has two types of temperature coefficient, i.e., the positive and the negative Thermistors are available in two types: PTC (positive temperature coefficient) and NTC (negative temperature coefficient). The resistance of a PTC thermistor increases as the temperature increases. In contrast, the resistance of an NTC thermistor decreases as temperature increases, and this type seems to be the most commonly used thermistor Negative temperature coefficient (NTC) thermistors are thermally sensitive semiconductor resistors which show a decrease in resistance as temperature increases. EPCOS brand NTC thermistors are simple, but very sensitive and accurate sensing elements for measuring and control temperature in circuits. Features and Benefits For example, a thermistor may be more sensitive at cooler temperatures than at warmer temperatures, as is the case with Wavelength's TCS10K5 10 kΩ thermistor. With the TCS10K5, the sensitivity is 162 mV per degree Celsius between 0°C and 1°C, and it is 43 mV / °C between 25°C and 26°C, and 14 mV °C between 49°C and 50°C Positive temperature coefficient thermistors are typically made of ceramic material that has been doped to create a semiconductor. These semiconductor PTC sensors have a non-linear resistance-temperature curve, and at a critical temperature (sometimes referred to as the switch temperature or Curie temperature), resistance increases significantly

Semiconductor thermistors operating in the variable range hopping conduction regime have been used in thermal detectors of all kinds for more than fifty years. Their use in sensitive bolometers for infrared astronomy was a highly developed empirical art even before the basic physics of the conduction mechanism was understood. Today we are gradually obtaining a better understanding of these. These thermometers measure temperature with a resistor (a ceramic semiconductor bonded in the tip with temperature-sensitive epoxy). The probe is approximately 1/8-inch thick and takes roughly 10 seconds to register the temperature on the digital display.
