Abstract: A method of providing sensing apparatus and a sensing method are disclosed. One aspect provides sensing apparatus comprising: a chamber configured to receive a biological sample at least part of a wall of the chamber comprising a printed circuit board substrate; the part of the wall comprising a printed circuit board substrate comprising an electrode configured to transmit or receive a signal to the biological sample, the electrode being coupleable to a sensing control unit located outside the chamber. The apparatus comprising a channel in communication with the chamber, the channel being dimensioned to allow at least a portion of the biological sample extend through the channel, the channel comprising a conductive surface configured to transmit or receive a signal to at least a portion of the biological cell sample extendable through the channel, the conductive channel surface being coupleable to the sensing control unit located outside the chamber.
