    Abstract Objective Models explaining technology acceptance fail to recognize the influence temporary, compulsory usage, meaning forced usage due to external factors, may have on user evaluation and continued diffusion. However, in context of the Covid-19 pandemic, a highly infectious respiratory disease, the significance of this factor is evident. Triggered by legal contact restrictions and extended reimbursement capacities, usage of telepsychotherapy increased drastically, thereby influencing therapists' attitude and increasing the technology's maturity. In this comprehensive literature review, we aim to outline the current state of research toward telepsychotherapy adoption and identify potential influences of the compulsory usage on the reevaluation of technology as well as barriers inhibiting and factors promoting future use. Methods The review was conducted on the five databases ScienceDirect, Web of Science, PubMed, PubPsych, and IEEE up to April 2022. Results Out of 685 identified references, a final selection was made of 22 papers, discussing experiences with telepsychotherapy in the context of the Covid-19 pandemic. Satisfaction and intention to use are universally high, further increasing with time and use experience, while perceived challenges decrease. Barriers include mostly contextual factors, such as technical issues, reimbursement issues, strict regulations, insufficient infrastructure, and lack of organizational support, but also concerns regarding efficacy. Promoting factors are training, guidelines, and organizational support. Conclusions Telepsychohtherapy has become an integral part of psychotherapeutic care. A hybrid system in close coordination between provider and patient may prevail, addressing individual needs of both parties to achieve optimal care and provider well-being. This requires transparent regulations, guidelines, and standards.

    Abstract Abstract A large and growing number of applications benefit from simple, fast and highly sensitive 3D imaging sensors. The Focus-Induced Photoresponse (FIP) can achieve 3D sensing functionalities by simply evaluating the irradiance dependent nonlinear sensor response in defect-based materials. Since this advantage is intricately associated to a slow response, the electrical bandwidth of present FIP detectors is limited to a few $${\text{kHz}}$$ kHz only. The devices presented in this work enable modulation frequencies of 700 kHz and beat frequency detection up to at least 3.8 MHz, surpassing the bandwidth of reported device architectures by more than two orders of magnitude. The sensors achieve a SNR of at least $$\sim 53\;{\text{dB}}$$ ∼ 53 dB at $$115\;{\text{cm}}$$ 115 cm and a DC FIP detection limit of 0.6 µW/mm2. The mature and scalable low-temperature a-Si:H process technology allows operating the device under ambient air conditions waiving additional back-end passivation, geometrical fill factors of $$100\%$$ 100 % and tailoring the FIP towards adjustable 3D sensing applications.
