The application relates to a chemical monitoring system comprising a skin patch for detecting an analyte in perspiration and a processor adapted to receive parameter data and to return an output indicative of a presence of an analyte in a subject's body based on the parameter data. The skin patch 100 includes a first layer 105 permeable to perspiration; a second layer 110 coupled to the first layer, the second layer being adapted to receive the perspiration; wherein a property of the second layer changes upon receiving the analyte; an electrical detector coupled to the second layer, adapted to detect parameter data indicative of the property of the second layer; and a flexible electronic circuit 140 coupled to the second layer, comprising a readout circuit for reading parameter data from the electronic detector and a transmitter adapted to transmit the parameter data to a processor. The transmission may be through a radio frequency device. The second layer may be functionalized, contain a polymer matrix, get matrix or polymer layer or have a plurality of probes which interact with the analyte. |
