An electroconductive film (101) comprises a metal thin-film (10) on a first main surface of a flexible substrate (40) that includes a resin film (5). The thickness of the flexible substrate is 1 mm or less. The absolute value [H.sub.2−H.sub.1] of the difference between the heating dimensional change rate H.sub.1 of the electroconductive film and the heating dimensional change rate H.sub.2 of a film obtained by removing the metal thin-film from the electroconductive film is preferably 0.10% or less. There is a tendency that undulation of a temperature sensor film after patterning of the metal thin-film is further suppressed as the value of [H.sub.2−H.sub.1] decreases.

The bandgap-less apparatus is a fast settling circuit (e.g., with settling time of less than 40 ns) that can leverage proportional-to-absolute-temperature only (PTAT-only) currents to generate a zero or substantially zero temperature coefficient, or even complementary-to-absolute-temperature (CTAT), reference current or voltage, without the need of a native CTAT component or bandgap diodes. The apparatus subtracts two different PTAT currents so that the resulting current is zero-TC. The resulting current is a reference current. The resulting current can be converted to a reference voltage.

A system may include a transformer that may convert a first voltage to a second voltage, such that the second voltage is output via a conductor. The system may also include a wireless current sensor that may detect current data associated with current conducting via the conductor and a processor.

A medical ultrasound device is disclosed. The device comprises an elongated body having a proximal end, a distal end (10) and a distal end region (1). One or more ultrasound transducers (4) for generating acoustic radiation are positioned in the distal end region, inside the elongated body. A transmission element (5) which is substantially transparent to acoustic radiation is positioned in the radiation path of the acoustic radiation, and a controller unit is operatively connected to the ultrasound transducer.
