“…The latest developments will enable environmental monitoring drones to be fully biodegradable and therefore enable environmental sensing one-way missions. While various approaches toward manufacturing and material selection are discussed in literature, [50,51] especially the development of transient transistors [52,53] will allow higher levels of autonomy for the drone. Nevertheless, the herein-developed platform can be used to carry various transient sensing devices, such as humidity or UV-intensity sensors.…”

Natural forests are one of the world's largest carbon sinks, absorbing approximately two billion tonnes of CO 2 per year. [1,2] To improve understanding of forest ecosystems and develop conservation strategies, more sophisticated energy balance models need to be developed. [3] Research activities must focus on understanding changes in the vegetative phenology and the ecosystem energy or mass exchanges, which influence the ecosystem carbon production and productivity levels. [4][5][6] Many factors need to be studied and modeled to estimate CO 2 budgets [7] and guide policymakers and environmentalists toward efficient strategies for carbon sequestration in forests. [8] To develop these models, environmental data with high temporal and spatial resolution is of the utmost importance. This requires time-consuming, complex, and expensive methods to manually distribute build-to-last sensing devices with human workers. [9] These sensing devices still pose a threat to the environment in which they are deployed in, as they are nondegradable and potentially toxic.

“…This is particularly important for biodegradable materials as they are generally sensitive to humidity, heat and prone to oxidation, and thus compatible fabrication processes that can be conducted under ambient conditions are favourable. [118][119][120] Laser-ablation techniques are particularly adapted to process a variety of transient organic and inorganic materials as they minimise the risk of degradation of the material through oxidation during fabrication 80 and were used to pattern kirigami structures for the stretchable and biodegradable battery materials mentioned in Section 3.1. Recently, this method was also used to engineer intricate 3D micropillar active electrodes on metallic serpentine structures to assemble a stretchable microbattery with a high areal capacities of 2.5 mA h cm −2 .…”

“…To this end, a library of biodegradable materials with useful electronic properties has been identified; however, the majority of research on green device manufacture still relies on conventional microfabrication techniques [4][5][6][7] . Nevertheless, printed electronics offer an eco-friendly alternative to microfabrication in situations where scalability, cost-effectiveness and low material waste are preferred 8,9 .…”

“…Nevertheless, printed electronics offer an eco-friendly alternative to microfabrication in situations where scalability, cost-effectiveness and low material waste are preferred 8,9 . Combining these efforts to produce printable biodegradable electronics has found success for conductive materials (Zn, Mo, carbon) as well as inorganic (MgO and SiO 2 ) and organic (Polyvinyl alcohol, cellulose and silk) insulating materials 6,7,[10][11][12] . However, work still remains for more specialised electronic components.…”

Low-temperature processing of screen-printed piezoelectric KNbO3 with integration onto biodegradable paper substrates

The development of fully solution-processed, biodegradable piezoelectrics is a critical step in the development of green electronics towards the worldwide reduction of harmful electronic waste. However, recent printing processes for piezoelectrics are hindered by the high sintering temperatures required for conventional perovskite fabrication techniques. Thus, a process was developed to manufacture lead-free printed piezoelectric devices at low temperatures to enable integration with eco-friendly substrates and electrodes. A printable ink was developed for screen printing potassium niobate (KNbO3) piezoelectric layers in microns of thickness at a maximum processing temperature of 120 °C with high reproducibility. Characteristic parallel plate capacitor and cantilever devices were designed and manufactured to assess the quality of this ink and evaluate its physical, dielectric, and piezoelectric characteristics; including a comparison of behaviour between conventional silicon and biodegradable paper substrates. The printed layers were 10.7–11.2 μm thick, with acceptable surface roughness values in the range of 0.4–1.1 μm. The relative permittivity of the piezoelectric layer was 29.3. The poling parameters were optimised for the piezoelectric response, with an average longitudinal piezoelectric coefficient for samples printed on paper substrates measured as d33, eff, paper = 13.57 ± 2.84 pC/N; the largest measured value was 18.37 pC/N on paper substrates. This approach to printable biodegradable piezoelectrics opens the way forward for fully solution-processed green piezoelectric devices.
