The display of the future is multimodal, integrating optical sensors, RFID antennas, ultrasound transducers, etc. The sensors produce a large amount of redundant data, which should be preprocessed on the substrate, ideally on the backpanel. Control gates and select and data drivers need to be more configurable and partitionable to create operational flexibility. This paper presents various circuit blocks for processing and control, including operational amplifiers, high-resolution analog-to-digital converters, a microprocessor, DC-DC converters, and high resolution sensor pixel array architectures. Moreover, the performance of the basic building blocks is compared in LTPS and IGZO technology.

Sensing and Identification systems operating in harsh environments represent a challenge for designers and manufacturers due to the unconventional operative conditions and the multiple mechanical solicitations to which they are exposed. Usually, when applied in this scenario, circuits and antennas suffer damage and failure of conductive traces, bondings, and substrates, leading to malfunctioning and even stopping functioning.

Recent advances in flexible and stretchable electronics have attracted great attention due to its potential applications to personalized bio-integrated healthcare devices. The mechanical mismatch between conventional rigid electronic devices and soft human tissues oftentimes causes various issues, such as a low signal-to-noise ratio of biosensors, inflammations on the tissue interfacing with the bioelectronics, skin irritations in the case of long-term wearing of the device, and ineffective electrical stimulations in feedback therapies.

Brain–computer interfaces (BCIs) facilitate direct communication between the brain and external computers, with applications spanning neuroscience, medicine, and virtual reality. Current BCIs are, however, based on conventional rigid electronics and are limited by their intrinsic mechanical and geometrical mismatch with brain tissue. Flexible electronics, which can have mechanical properties compatible with the brain, could address these limitations and be used to create the next generation of BCI systems.
