Activation of a digital watch (as a model device) by the implanted biofuel cells

Activation of a pacemaker by the implantable biofuel cells mimicking human physiology

Good news – the pacemaker operation was perfect !!!

Bad news – the system included 5 biofuel cells with serial connection

Powering pacemaker from a single implantable biofuel cell through a charge pump (A) Experimental setup which includes (from left to right): (a) sensor device for the Medtronic CareLink Programmer, Model 2090, (b) Medtronic Reveal XT, Model 9529, implantable loop recorder (ILR), (c) Affinity DR 5330L, St. Jude Medical, pacemaker, (d) the charge pump–DC-DC interface circuit, (e) the flow biofuel cell with the inlet/outlet connected to a peristaltic pump (not shown in the scheme). (B) Registered pulses generated by the pacemaker when it is powered by the standard battery. (C) Registered pulses generated by the pacemaker when it is powered by the biofuel cell. Standard battery Biofuel cell

C NH O Bioelectrocatalytic electrodes operating in vivo can be used for many different bioelectronic and biosensor applications Electrode Power from biofuel cell Information from biosensor Fuel Analyte
