## Abstract

The disclosed systems and methods provide a mobile defibrillator system that can include a mobile defibrillator (AED) unit configured to operatively connect to a device capable of running an application. The mobile AED unit can include circuitry for administering an electric shock to a subject; and one or more pads. Each pad can include one or more needles electrically connected to the circuitry and can be configured to pierce skin of the subject; reside within the subject; and deliver current from the electrical shock to the subject.

## Claims

### Claim 1

A mobile defibrillator system comprising:
a mobile defibrillator (AED) unit configured to operatively connect to a device capable of running an application, the mobile AED unit comprising:
circuitry for administering an electric shock to a subject; and
one or more pads, each pad comprising one or more needles electrically connected to the circuitry and configured to:
pierce skin of the subject;
reside within the subject; and
deliver current from the electrical shock to the subject.

### Claim 2 (depends on 1)

The mobile defibrillator system of claim 1, wherein the one or more needles comprise a metal material.

### Claim 3 (depends on 1)

The mobile defibrillator system of claim 1, wherein the one or more needles are curved.

### Claim 4 (depends on 3)

The mobile defibrillator system of claim 3, wherein the one or more needles are curved away from the subject.

### Claim 5 (depends on 1)

The mobile defibrillator system of claim 1, wherein the one or more needles are configured to reside within subcutaneous tissue of the subject.

### Claim 6 (depends on 1)

The mobile defibrillator system of claim 1, wherein the one or more pads are foldable.

### Claim 7 (depends on 1)

The mobile defibrillator system of claim 1, wherein the one or more needles are configured to be activated in response to an indication received from the device.

### Claim 8 (depends on 7)

The mobile defibrillator system of claim 7, wherein the indication is generated based on detecting an impedance between the one or more pads and the subject above a predefined threshold.

### Claim 9

An electrode for operation within a mobile defibrillator system comprising:
a cord configured to receive power for administering an electrical shock in connection with circuitry of a mobile defibrillator (AED) unit; and
a pad comprising one or more needles electrically connected to the circuitry and configured to:
pierce skin of the subject;
reside within the subject; and
deliver current from the electrical shock to the subject.

### Claim 10 (depends on 9)

The electrode of claim 9, wherein the one or more needles comprise a metal material.

### Claim 11 (depends on 9)

The electrode of claim 9, wherein the one or more needles are curved.

### Claim 12 (depends on 11)

The electrode of claim 11, wherein the one or more needles are curved away from the subject.

### Claim 13 (depends on 9)

The electrode of claim 9, wherein the one or more needles are configured to reside within subcutaneous tissue of the subject.

### Claim 14 (depends on 9)

The electrode of claim 9, wherein the one or more pads are foldable.

### Claim 15 (depends on 9)

The electrode of claim 9, wherein the one or more needles are configured to be activated in response to an indication received from the device.

### Claim 16 (depends on 15)

The electrode of claim 15, wherein the indication is generated based on detecting an impedance between the one or more pads and the subject above a predefined threshold.
