WIPO Patent Application WO/2020/066094
Kind Code:
A1
Abstract:
This in-vivo implantation-type electronic device (10A) is provided with a case (11), a power receiving coil (15), and an electronic circuit. The case (11) is formed from a biocompatible material and forms a sealed internal space. The power receiving coil (15) is arranged in the internal space of the case (11) and interacts with the electromagnetic field formed from an external electric field or magnetic field to receive power, or externally transmits electromagnetic waves. The electronic circuit is arranged in the internal space, is connected to the power receiving coil (15), and performs at least electrical signal processing. Further, the case (11) is provided with: a box-shape first member (111) which is formed from a metal-base biocompatible material and which has an opening; a second member (112) which is formed from a non-metal-base, biocompatible material and which has a shape that closes the opening; and an annular packing (115) which is arranged between the first member (111) and the second member (112).
