1. An apparatus comprising:
a flexible substrate; and
circuitry fabricated on the flexible substrate to perform data processing, wherein the circuitry comprises:
at least one strain detector arranged to generate a strain signal which is dependent on a flexing state of the strain detector on the flexible substrate; and
a strain history control unit arranged to sample the at least one strain signal from the at least one strain detector at a plurality of time points and to record a strain snapshot at each time point comprising data dependent on the at least one strain signal from the at least one strain detector,
wherein the apparatus is configured to modify data processing operations performed by the circuitry in dependence on the plurality of strain snapshots recorded.
