An early technology demonstration was shown in the Prinse 20 seminar end of January at VTT in Oulu Finland. There the Imec Museic evaluation board was connected with printed electrodes in the targeted patch form factor to measure ECG in wrist. The result is shown in Figure 1.

The next version of technology demonstrations for skin patches will utilize several functional layers integrated as a vertical stack structure as schematically illustrated in Figure 2.
