Tactile sensing is required for assistant robots. A new stacked sensor head was proposed which detects forces and thermal sensations with a nerve-net LSI chip. To measure temperatures and heat flows, the sensor head required a thin and small heater to heat up the sensor head. The features of the polyimide heater are compact, low heat capacity, low power consumption and ease of attaching it to t...

In an induction heater for heating of aluminum billets, the main reason for using high-temperature superconducting (HTS) tapes instead of conventional copper conductors is to reduce the large power losses in the induction coil. In this work we present how to calculate the different loss contributions of an induction heater based on HTS tapes. Calculations of these losses are used in the design ...

A downhole electric tubular resistive heater is proposed for the oil-shale in situ resorting. After flowing through a set of heating tubes, outlet temperature and flow rate injected gas can be conveniently adjusted to match requirement pyrolysis oil shale. The calculation demonstrates effects inner diameter, length tube, inlet on heat transfer performance heater. It was found that, compared wit...

The heater temperature was calibrated using the measurement of the electrical resistance of the heater using the circuitry shown in Fig. S2 a. During the experiments a constant bias, Vtot is applied. The electrical resistance is measured from the voltage drop across the heater. The resulting current–voltage diagram is shown in Fig. S2 b. The electrical resistance changes as a function of the po...

A thermogenic organ is found beneath the brain of billfishes (Istiophoridae), swordfish (Xiphiidae) and the butterfly mackerel (Scombridae). The heater organ has been shown to warm the brain and eyes up to 14 degrees C above ambient water temperature. Heater cells are derived from extraocular muscle fibers and express a modified muscle phenotype with an extensive transverse-tubule (T-tubule) ne...

As an important auxiliary unit of Modern large-scale thermal Power Unit, the performance high-pressure feedwater heater will directly affect whole unit. This paper introduces calculation method exergy efficiency heater, and compares with system a 1000MW The results show that can clearly reflect change when terminal difference changes, give new work energy saving emission reduction.
