## Abstract

A leakage detection system is provided and includes a substrate provided between a first element and a second element, and at least one sensing unit provided on the substrate to generate an electrical signal when coming into contact with a leakage liquid. As such, warnings can be provided when coming into contact with the leakage liquid to avoid significant loss of assets.

## Claims

### Claim 1

A leakage detection system, comprising:
a substrate provided between a first element and a second element;
at least one sensing unit provided on the substrate for generating an electrical signal when coming into contact with a leakage liquid; and
an absorbent layer provided between the first element and the second element for absorbing the leakage liquid of the first element or the second element and guiding the leakage liquid to the sensing unit.

### Claim 2 (depends on 1)

The leakage detection system of claim 1, further comprising at least one connector connecting the first element and the second element and surrounded by the substrate, the sensing unit and the absorbent layer.

### Claim 3 (depends on 2)

The leakage detection system of claim 2, wherein the substrate and the sensing unit are positioned between the at least one connector and the absorbent layer.

### Claim 4 (depends on 3)

The leakage detection system of claim 3, further comprising an isolation layer provided on an outer side of the absorbent layer for preventing external liquids from penetrating into the absorbent layer.

### Claim 5 (depends on 4)

The leakage detection system of claim 4, further comprising a barrier layer provided on an outer side of where the isolation layer joins with the first element for preventing the leakage liquid.

### Claim 6 (depends on 2)

The leakage detection system of claim 2, wherein the first element is a pipe, the second element is a liquid cooling device, and the connector connects the pipe and the liquid cooling device.

### Claim 7 (depends on 1)

The leakage detection system of claim 1, further comprising:
a processing module coupled to the substrate and the sensing unit via a signal line for generating a warning signal upon receiving the electrical signal, the warning signal being transmitted to a buzzer on a circuit board via another signal line coupled between the processing module and the circuit board or transmitted to a software interface.

### Claim 8 (depends on 1)

The leakage detection system of claim 1, wherein the sensing unit is a capacitive or a resistive humidity sensor.
