the aim to circumvent the intermittency of these dynamic resources and provide power supply on demand, energy storage systems that can effectively store the elec trical energy are strongly demanded. [5][6][7] Among numerous electrical energy storage (EES) devices available today, lithium batteries, capacitors, and super capacitors are particularly appealing owing to their large capabilities of storing energy with long service lifetime. [8,9] In recent years, with the rapid development of mate rial science and nanotechnology, energy storage devices with enhanced performance have been realized, [2,[6][7][8][9][10] and they have emerged as the dominant power sources for portable electronics in modern society. Despite the advances already achieved, per formance of these EES devices still needs to be further improved in order to meet the higher requirements of future systems, ranging from microelectrochemcial sys tems (MEMS) to electrical transportation systems like electric vehicles.The development of the electrode mate rials is essential for the improvement of high performance EES systems. [11,12] Noticeably, nanomateirals derived from rolledup nanotechnology have attracted world wide interest recently, and remarkable progress has been made when introducing this technology into the design of energy storage devices. [13][14][15][16][17][18][19][20][21][22][23][24][25] In particular, nanostructures prepared by rolledup nanotechnology offer controllable surface area, short charge diffusion distance, and large freedom for volume change during charge/discharge cycles. In this sense, rolledup nano structured materials can be expected to improve the energy den sity, life cycle, and rate capability of lithiumbased batteries. In addition, the high compatibility with lithography and physical vapor deposition techniques makes rolledup nanotechnology suitable for labonachip EES device fabrication as well as other tremendous integrative devices applications. [26][27][28][29][30] In this report, we focus on the recent progress of using rolledup nanostructured materials as electrodes to develop advanced EES devices, including Liion batteries (LIBs) and LiO 2 batteries. In addition, single tube based EES micro devices as diagnostic electrochemical probes for basic mechanistic investigations are summarized. Notable progress of introducing rolledup nanotechnology into the design of scalable and ultra compact electrostatic capacitors with superior performance is also reviewed. Finally, future trends of applying rolledup nanotechnology to other potential applications, such as scalable Energy storage devices, acting as complementing units for renewable energy sources, play a key role in modern society, and they serve as the dominant power supply for most portable electronics. At the heart of the development of next-generation energy storage devices lies the exploration of intrinsic material properties, architectural design and fabrication methods.

Glucose biofuel cells (GBFCs) are highly promising power sources for implantable biomedical and consumer electronics because they provide a high energy density and safety. However, it remains a great challenge to combine their high power density with reliable long-term stability. In this study, a novel GBFC design based on the enzyme biocatalysts glucose dehydrogenase, diaphorase, and bilirubin oxidase immobilized in rolled-up titanium nanomembranes is reported. The setup delivers a maximum areal power density of ≈3.7 mW cm and a stable power output of ≈0.8 mW cm . The power discharges over 452 h, which is considerably longer than reported previously. These results demonstrate that the GBFC design is in principle a feasible and effective approach to solve the long-term discharge challenge for implantable biomedical device applications.

“…On the contrary, recent research efforts establish an impressive alternatives to commercially available cylindrical, coin, prismatic, and pouch cells with flexible and stretchable batteries. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] Nevertheless, such advances do not address the major necessities for implantable devices, especially in orthodontic dental implantations, which generally require: smaller footprint, lightness, high bio-compatibility, and finally integration strategy with other circuit components. Here, we show, a high yield, transfer-less method to achieve a bio-compatible, flexible, high-performance solid-state, micro-battery for wearable and implantable device electronics, specifically with an example potentially disruptive for orthodontics applications.…”

To augment the quality of our life, fully compliant personalized advanced health-care electronic system is pivotal. One of the major requirements to implement such systems is a physically flexible high-performance biocompatible energy storage (battery). However, the status-quo options do not match all of these attributes simultaneously and we also lack in an effective integration strategy to integrate them in complex architecture such as orthodontic domain in human body. Here we show, a physically complaint lithium-ion micro-battery (236 μg) with an unprecedented volumetric energy (the ratio of energy to device geometrical size) of 200 mWh/cm 3 after 120 cycles of continuous operation. Our results of 90% viability test confirmed the battery's biocompatibility. We also show seamless integration of the developed battery in an optoelectronic system embedded in a threedimensional printed smart dental brace. We foresee the resultant orthodontic system as a personalized advanced health-care application, which could serve in faster bone regeneration and enhanced enamel health-care protection and subsequently reducing the overall health-care cost.
