Advanced electrochemical methods for surface characterisation such as cyclic voltammetry and chronopotentiometry have also been used to detect specific target binding of immobilised nucleotides on gold surfaces. Apart from mechanical and electrical readout, optical readout is also demanded by a number of bioMEMS devices. Wavelengths used span from ultraviolet to infrared and bio-probes are often attached to optical fibres to aid measurements. Species absorption onto gold/silver as well as change in refractive index can be measured through Surface Plasmon Resonance (SPR) [83].

Most of the existing biodegradable devices, either used clinically or in laboratory development, are passive and without the sensing or actuation capabilities. To address this limitation, it is necessary to develop bio-fragmentable or resorbable electronics to fulfil the transient sensing capabilities. Recent work by John Rogers and team have demonstrated a physically transient form of silicon electronics for this purpose [96]. They have experimented with a set of materials and manufacturing schemes.
