Implants must protect against implant contamination and corrosion of electronics. However, when electrical components are fitted to flexible substrates, failure can occur at electrical connections.An implant comprises: a flexible substrate; a first and second electrical component at a first and second position, electrically connected through an interconnect layer; a first and second component cover, separately encapsulating the first and second component to resist the ingress of body fluids into the component positions; wherein the flexible substrate allows a relative change in disposition between the first component cover and the second component cover. One or more electrodes are provided at a third position.By encapsulating each component separately, the position of force/tension is moved away from the component attachment position to a point somewhere between the component positions. By disposing one or more electrode away from the components, the ingress is further restricted.
