摘要：
There is an implantable medical device (20) comprising an acousto-optic transducer (200), a photodetector (300), and an optical communication channel (400) connecting an output of the acousto-optic transducer (200) to an input of the photodetector (300). The components of the implantable medical device (20) can be made sufficiently small that they can be implanted into a living subject with ease and require no external power supply. Since the acousto-optic transducer (200) can receive acoustic signals, which are transmissible through bone, the device (20) can be implanted into a living bone and can be communicated with transdermally. There is also a wireless communication system comprising such an implantable medical device (20) and an electro-acoustic transducer (30a, 30b, ... 30n) able to transmit information to the implantable medical device (20) by transdermal transmission of an acoustic signal. Such a system is particularly suited to the repair of spinal injuries. A method of transdermal wireless communication is also provided, comprising transmitting an acoustic signal from outside a human or animal subject, receiving the acoustic signal within the human or animal subject, and converting the acoustic signal into an optical signal, as well as a method of in vivo communication, comprising transmitting an acoustic signal within a human or animal subject, and converting the acoustic signal into an optical signal. Preferably, the acoustic signal is converted into an optical signal using Förster resonance energy transfer (FRET) from a donor molecule to a receptor molecule within the acousto-optic transducer (200).
