Constructions for zero-heat-flux, deep tissue temperature measurement devices |
摘要 |
The invention pertains to flexible devices used for zero-heat-flux, deep tissue temperature measurement, especially to disposable temperature measurement devices. Such a device is constituted of a flexible substrate. An electrical circuit is disposed on a side of the substrate. The electrical circuit includes first and second thermal sensors disposed, respectively, on first and second substrate layers. A heater trace is disposed on the first substrate layer with the first thermal sensor. The first and second substrate layers are separated by a flexible layer of insulation disposed between the first and second substrate layers. The heater trace defines a heater with a central portion that operates with a first power density and a peripheral portion around the central portion that operates with a second power density greater than the first power density. |

1. A zero-heat-flux temperature device with first and second flexible substrate layers sandwiching a layer of thermally insulating material, in which a heater trace disposed on the first substrate layer defines a heater including a central power density portion surrounding a zone of the first substrate layer having no heater trace and a peripheral power density portion surrounding the central power density portion, a first thermal sensor is disposed in the zone, a second thermal sensor is disposed on the second substrate layer, a plurality of connection pads is disposed outside of the heater trace, and a plurality of conductive traces connects the first and second thermal sensors and the heater trace with the plurality of connection pads. |
