1. A wearable electronic device comprising: (5) (3)

a molded body part made of a moldable ceramic material, having an inner surface and an outer surface, wherein at least one cavity having a depth is arranged on the inner surface of the body part,

an electronic part arranged in said cavity, which electronic part has a thickness that is less than the depth of the cavity, and

a coating made of a moldable filler material on the inner surface of the body part, covering the electronic part and the cavity.

2. The wearable electronic device according to claim 1, wherein the moldable ceramic material is selected from a group consisting of zirconium, aluminum nitride, aluminum oxide, boron carbide, silicon carbide, silicon nitride, titanium diboride and yttrium oxide. (0)

3. The wearable electronic device according to claim 1, wherein the electronic part is attached to the cavity by an attachment means arranged at a bottom of the cavity. (1) (0)

5. The wearable electronic device according to claim 1, wherein the moldable filler material is selected from a group consisting of at least epoxy material, Polyethylene, Polyurethane, low temperature moldable material, Loctite M-31CL, alpha-epoxy, 1,2-epoxy, EpoxAcast® 650, Bisphenol S epoxy resin, Novolac epoxy resin, Aliphatic epoxy resin and Glycidylamine epoxy resin. (0)

6. The wearable electronic device according to claim 1, wherein the electronic part comprises a battery, an infrared transmitter, a microcontroller, a radio frequency transceiver, a temperature sensor and an infrared receiver. (1) (0)

7. The wearable electronic device according to claim 1, wherein the moldable filler material comprises an ink, which ink increases value of transmitted infrared light intensity divided by transmitted visible light intensity. (0)

9. A method for manufacturing a wearable electronic device, comprising the steps of: (5) (3)

molding a body part using a moldable ceramic material, wherein a mold is such that at least one cavity is formed on an inner surface of the body part,

arranging an electronic part in said cavity, and

coating the inner surface of the body part to form the coating, including covering the electronic part.

10. The method according to claim 9, wherein the electronic part is attached to the cavity using an attachment means arranged on a bottom of the cavity. (0)

11. The method according to claim 9, wherein the step of arranging the electronic part in the cavity is carried out using an assembly guiding element. (0)

12. The method according to claim 9, wherein the mold is such that two cavities, a first cavity and a second cavity, are formed on the inner surface of the body part. (2) (0)

15. The method according to claim 9, wherein the coating the inner surface of the body part is done by applying an epoxy resin on the surface and curing the resin to form an epoxy coating. (1) (0)

17. The method according to claim 9, wherein the step of coating the inner surface of the body part is carried out using a molding stand. (0)
