- Аннотация: Self-powered sensors are among promising candidates for wake-up device elaboration. Generally, such sensors are designed to generate superior energy output to the detriment of analytical performance. Here we report on power output of Prussian Blue (PB) based (bio)sensors retaining advanced analytical performance in power generation mode. The maximum power density is linearly proportional to analyte concentration: the slopes for hydrogen peroxide sensor and glucose biosensor are of 37 mW M−1 cm−2 and 3 mW M−1 cm−2, respectively. The cells consisted of power generating (bio)sensors are able to switch on a light-emitting diode (LED) at threshold concentration of 0.6 mM H2O2 or 8 mM glucose that is suitable for naked-eye semiquantitative analysis. The presented prototype of signaling device is expected to have significant impact on the development of autonomous wake-up sensors for medical, industrial or environmental monitoring.
