“…The danger of infection is an evident disadvantage, which was reduced by telemetric data transfer powered by batteries [20,21]. Due to the limited life time of batteries, the required space and the risk of leakage, energy transmission by electromagnetic fields was developed [14,[32][33][34]. The dependency on permanent equipment outside of the human body is still a disadvantage that limits the use to temporary experimental or clinical applications.…”

To improve the clinical outcome of total hip replacements (THRs), instrumented implants with sensory functions for implant monitoring and diagnostics or actuators for therapeutic measures are a promising approach. Therefore, an adequate energy source is needed. Batteries and external power supplies bring shortcomings e.g. limited lifetime or dependency on external equipment. Energy harvesting has the clear benefit of providing continuous and independent power for fully autonomous implants. Our present study evaluates by means of finite element analysis (FEA) the capabilities of a concept of a piezoelectric energy harvesting system (ring shaped multilayer piezoelectric element of 5 mm diameter and 2.5 mm height) integrated in a femoral hip stem. The deformations from a modified load-bearing implant are used to generate electric power for various instrumentation purposes. Besides the expected amount of converted energy, the influence on the stress distribution of the instrumented implant is analysed. The results show that the local stress increase for the modified implant geometry does not exceed the stress of the original reference model. The maximum generated open circuit voltage of 11.9 V can be processed in standard energy harvesting circuitry whereas an average power output amounts up to 8.1 µW. In order to increase the electric power in an upcoming design optimization, a sensitivity analysis is performed to identify the most important influencing parameters with regard to power output and implant safety.

The introduction situates the question of gender in biographical fiction in relation to current scholarship on biofiction, life writing, and historical fiction, and establishes a dialogue between biofiction studies and gender-sensitive approaches to both life writing and historical fiction. Clarifying the often complex and contradictory understandings of key terms that have emerged in recent scholarship on biofiction, historical fiction, life writing, and their inter-relationships, the introduction discusses the ethics of biofiction and the notion of biographical authenticity; the persistence of conventional tropes of femininity, masculinity, and gender normativity in biofiction; the aesthetics of agency in post-Lukácsian biofiction and historical fiction; and the role of creativity in imagining feminist, queer, and non-binary pasts.The introduction then outlines the volume’s individual chapters and the common themes or approaches that connect them, including gender and power relations in the re-imagined lives; critique or reinscription of patriarchal values and mindsets; cliché and generic convention; revision and reinvention; ventriloquism and visibility; uses of historical research, evidence, sources, and their traces in the biofictional text; narratological aspects; and questions of readership and reception.
