Wireless micromachine for in situ inspection of conduit inner walls - has energy conversion devices for converting different forms of energy e.g. radiation, microwaves into electrical energy

摘要

The micromachine includes a number of energy conversion devices (3, 5, 6, 7) which receive different forms of energy including radiation, microwaves and sound waves. The energy conversion devices convert the different forms of energy into electrical energy. A further device delivers the electrical energy from the energy conversion devices to an operating or driving system in the micromachine. In one embodiment a collecting device collects the electrical energy from the energy conversion devices. USE/ADVANTAGE - Can operate without external power supply wires e.g. for internally inspecting electrical cable and wiring conduits and oil and water pipes for condition of walling.
