Cell-phone Implant Modules

If you remove a cell phone’s plastic exterior, you’ll find all kinds of electronic components inside. Numerous chips and devices attach to a printed circuit board. These include:

A microprocessor, which acts like the phone’s brain
Flash memory and read-only memory (ROM)
Analog-to-digital and digital-to-analog converters
A radio transmitter and receiver
A speaker and a microphone
Connectors for the phone’s buttons, screens and antenna
Connections for charging cords and headsets
Some models have GPS and Bluetooth receivers. Many new phones also have built-in digital camera lenses and sensors, as well as storage space for pictures and videos. Some phones even have the circuitry and storage space required to store and play MP3s. The more parts there are and the more impressive the phone’s capabilities, the larger and stronger the phone’s battery has to be. In many cell phones, the battery as almost as large as the printed circuit board it powers.
Combined, the circuit board, its components and the battery make up about half of the phone’s bulk. The rest comes from the screen, the keys and the outer plastic case. Since an implant has to be much smaller than a traditional cell phone, a good first step in making one is getting rid of these three elements. For this reason, a cell-phone implant does not have a typical user interface (UI). It uses the person’s body instead.

Taking the place of a keypad is a six-axis piezoelectric accelerometer attached to the angle of the mandible, or the jawbone. This accelerometer can detect when the jaw opens and closes or moves from side to side. Since the jaw moves along with a person’s head, the accelerometer also detects head movements. It does this using crystals that create electrical pulses when they change shape. You can read How the Nike + iPod Works to learn more about these crystals.
The implant’s on/off switch

After receiving the cell-phone implant, the user learns a series of head and jaw gestures that control the phone. This is similar to the stylus shorthand used with older PDAs. It’s also a little like sign language, but it uses the head and jaw instead of the hands. Before beginning a gesture, the user touches a small on/off switch located on the mastoid process, a bony protrusion on the skull just behind and below the ear. This lets the implant know to be ready for the user’s input and prevents it from mistaking ordinary conversation or movement for gestures. The user can also turn the implant completely off by holding the switch down for three seconds.
The modules of a cell-phone implant are inserted under the skin and in the jaw. During a gesture, a flexible circuit and conductive ink carry the accelerometer’s electrical impulses to the implant’s microprocessor, located on the back of the ear. This processor, made of a flexible thin-film transistor, is a custom-fitted piece that lies precisely along the cartilage in the back of the ear. The processor uses a lookup table stored on a nearby ROM chip to match a person’s movements with the cell phone’s commands. If a person makes the gesture for “four,” the processor finds the corresponding pattern of electrical impulses in the lookup table. It then holds the number four in a memory buffer until all of the gestures are complete. An implanted radio frequency (RF) transmitter sends the data using radio waves. This data moves just like ordinary cell phone data

 

Thin-film Transistors
If your current cell phone has an LCD screen, it probably uses thin-film transistors (TFTs) to power its pixels. The TFTs used in cell-phone implants are a little different, though. The TFT in an LCD screen is under a pane of glass, so it’s rigid. The TFTs used in cell-phone implants, on the other hand, are attached to flexible film. This technology, developed by the U.S. Air Force research lab, was originally intended to provide soldiers with flexible, wearable displays.

Standalone Implantable Medical Power Module – Patent 7009362

Disclosed is a medically implantable integrated biocompatible power module incorporating a power source (e.g., battery), a power management circuit (PMC), a magnetically inductive coupling system (MICS) for remote communication and/or inductive charging and a homing device for locating the implanted inductive charging coil. Three configurations are disclosed, each generally suitable for a specified range of energy capacities. The implantable power module (IPM) allows for improved design flexibility for medical devices since the power source may be located remotely and be recharged safely in situ. Special safety aspects may be incorporated, including endothermic phase change heat absorption material (HAM), emergency energy disconnect and emergency energy drain circuits. Communication (one or two way) may be carried out using the inductive charging link, a separate inductive pathway, or other pathway such as RF or via light waves. Homing devices and other means for precisely locating the IPM and/or MICS are disclosed.

Inductive Charging System – Patent 7211986

An apparatus for inductive charging a battery. The apparatus includes a housing with a lower surface and a charging surface. A rechargeable device with a rechargeable battery may be placed on the charging surface. The apparatus further includes a controller for driving an oscillator, wherein the controller receives power from a power source. A first charger coil and second charger coil are disposed within the housing and are coupled to the oscillator. The first charger coil and second charger coil create a substantially horizontal magnetic field in the volume of space above the charging surface.

Cortically based visual neuroporsthesis systems

The Intelligent Retinal Implant System (IRIS):

The implantable Retinal Stimulator consists of a flexible plastic film onto which various microelectronic components are mounted. The electronics are used to receive the stimulation data and to generate the electric pulses for stimulation. The microcontacts
(miniaturized electrodes) are used for stimulation. To bypass the degenerated part of the retina, stimulation pulses are applied by the microcontacts directly to the retinal ganglion cells which in turn pass the information via the optic nerve to the central nervous system.

The Visual Interface looks externally like a pair ofsunglasses. Several electronic components areintegrated into the glasses: a camera to capture images as well as other components for data communication with the Pocket Processor and the Retinal Stimulator. Furthermore, the Visual Interface transfers the energy required by the implant / Retinal Stimulator to the inside of the eye wirelessly. The pocket processor is connected with the Visual Interface using a thin cable.

The Pocket Processor has the size of a walkman. Itcontains rechargeable batteries which supply energy for the entire system (Pocket Processor, Visual Interface and Retinal Stimulator). It also contains a micro-computer that translates the image data from
the Visual Interface into stimulation commands for the Retinal Stimulator. Depending on the preference of the user, the Pocket Processor can be carried on a belt or a shoulder strap.

Retinal based visual neuroprosthetic:

Is an epiretinal approach where an electrode array will be placed on the vitreal surface in an effort to stimulate ensembles of ganglion cells (or possibly bipolar cells), and a subretinal approach where an electrode array is intended to be implanted between the retina and the pigment epithelium and extrinsic currents are intended to stimulate either remnant photoreceptor inner segments, or bipolar cells.

———————- ———————

Optic nerve based visual neuroprosthesis:

Phosphene generation via optic nerve stimulation. Implant with an extracellular ‘cuff’ electrode that surrounds the optic nerve, and containes four surface electrodes. Stimulation with various current levels through different combinations of electrodes would evoke a variety of spatially distributed phosphenes.

The Utah artificial vision system:

Consisting of a micro-video camera hidden in a pair of eyeglasses to transform light in the visual scene into electrical signals, signal processing electronics then converts these signals into patterns of electrical stimulation for the brain as well as a power source carried in a shirt pocket, a totally implanted multichannel stimulator with power and data to be delivered to the implant system via a radio-frequency telemetry link, and an electrode array with 625 microelectrodes.

****** Although not addressed in this paper, possible implementation of an additional Implantable Medical Power Module and Inductive Charging System may be applicable.
