as automotive, ID-cards and smart packaging. The simplified concept for the final demonstrators is

shown below, where the display in combined with energy harvesting modules (solar cell or/and

battery and power controller) and RFID communication or temperature sensor, in case of smart

i) System and sub-system definition and design.

ii) Definition of the characteristics pertaining to the sub-systems and validation protocols for

demonstrators assessment

iii) Electrical and geometrical design of the demonstrators

iv) Materials selection suitable to the assembling of the prototypes, including substrates

v) Definition of production processes for deposition and integration

multifunctional system. The specific objectives within this work are related to :

- electrochemical (electrochromic) thin film transistors (ECTFT) for future integration in display,

- flexible energy harvesting module (automotive and packaging),

- RF antenna coupled with IC for wireless communication.

Concerning this sub-project, in the last year were mainly focused

on:

• Upscaling (in a pilot line facility at ACREO) of the passive

electrochromic 8x8 passive matrix displays using printed WO3.• EC transistors for integration of EC active matrices

• Energy harvesting and storage subsystem, namely the

production of the batteries and selection of the PV cells to be

integrated in the demonstrators

•Optimization of the auxiliary electronics and communication

systems

All building blocks produced in SP3 were transferred to SP4. Before integration they were

tested to determine if they fit the specifications.

In the last year the electrochromic transistors (electrolyte gated with WO3 as channel layer)

were optimized and integrated in active matrix EC displays made by PVD at UNINOVA.

blocks optimized in SP3 by heterogeneous integration involving dry, wet processes and

lamination steps.




Co-integrated prototypes

built starting with different

backplane materials (PI,

PET, PC), for each type of

demonstrators (automotive,

packaging, ID card)

Co-integrated architecture prototypes

The fabrication of prototypes included the following steps: backplane development, pick&place,

lamination and vias interconnections.

From backplane CAD to

film produced by R2R is

shown. The film includes all

different demonstrators

backplane and all masks for

auxiliary and IC electronics

(BioAge and EMFT).

Convergence architecture prototypes

The final convergence integration architecture was composed by a thin film battery or hybridized

battery with an electrochromic device (powered by the battery) made using at least three

common materials (metal contacts, one electrode and the electrolyte). Two different convergent

subsystems were tested. The fabrication procedure involved a collaborative work between CEA,

UNINOVA and POLITO.

knowledge on design, deposition and integration processes developed in SP2, SP3 and SP4.

The high degree of multifunctionality of the novel self-powered flex devices is a key factor for

a potential application in: Autonomous systems for automotive, Multifunctional flexible foils

for ID-cards and Multifunctional flexible foils for smart packaging.

Symposium R – Towards flexible ion based devicesPartners UNINOVA, AVREO, CEA, POLITO and CRF have organize the

SMARTEC 2nd symposium, this time at the prestigious ERMS Spring

Meeting. The aim was to promote discussion among the international

scientific community dealing with this topic. The conference had

about 4000 attendees and several other running parallel symposiums

(30 in total, some on several topics related with SMART-EC, namely on

transparent conductors and electrochromic materials and devices).

The SMARTEC symposium had a 3 days program with more than 50

contributors coming from different countries including contributions

from SMART-EC consortium
