This paper presents a textiles based ferroelectret with enhanced energy harvesting performance by using a polymer with higher surface charge density and forming a optimize void structure. The textile ferroelectret is fabricated using a hot pressing process. The textile ferroelectret is made from two thin polyethylene terephthalate films and a thin layer of silk textile into a sandwich structure. Specifically, the ferroelectret generator, with piezoelectric coefficient d33 reaching 1600 pC/N, had worked stably for continuous about 10,000 cycles.

Textile based wearable, biocompatible and low-cost energy storage devices are highly in demand to overcome the issue of powering wearable sensors and electronic devices. In this work, we designed an environmentally friendly textile supercapacitor (SC) which operates with sweat equivalent electrolyte. For investigating the influence of conductivity of the electrodes we present two types of SCs which are based on electrodes of: (1) pure PEDOT: PSS and (2) PEDOT: PSS with DMSO. The increasing conductivity of PEDOT: PSS with DMSO shows significant influence performance enhancement of the SC. The SC exhibited a capacitance of 10 mF.cm−2 for PEDOT: PSS with DMSO and 3.8 mF.cm−2 for PEDOT: PSS in sweat equivalent solution. For a real human sweat the SC exhibited a capacitance of 9 mF.cm-2, thus showing the capability for powering the low-power wearable sensors.

Bio-integrated wireless systems require to integrate electronic modules for bio-signal processing within a stretchable and soft skin-like device. The size and complexity of the PCB hosting circuitry cannot be separated from the design of the antenna used for the communication. Challenges arise when high frequencies are involved so that human body losses will deteriorate the radiation gain. This paper describes the design of a UHF-RFID epidermal antenna integrated with different types of EMG-sensor board arrangements in comparison with a benchmark configuration. The purpose is to evaluate the effect of the PCB metallization and identify the optimal antenna size. An overall 40 $times 40mathrm{m}mathrm{m}^{2}$ device footprint is found to minimize the disturbing effects of the sensor circuit on the antenna performance and a read range up to 150 cm can be achieved.

This work reports the fabric-based supercapacitors (FSCs) using silver coated textile as the current collector. The electrochemical properties of the device in PVA-KCl gel electrolyte was studied. The performance of the device was further improved by printing an inhouse formulated graphite paste as the active electrode. The graphite printed Berlin fabric-based supercapacitor (BGr-FSC) shows an areal capacitance (CA) of 13.1 mF.cm−2, which is almost 4 times higher than the capacitance (3.53 mF.cm−2) of Berlin based FSC i.e. the one without graphite paste.

Integration of sensors with antennas is becoming popular for compact high-performance wireless sensing systems. In this direction, here we present a silver electrodes and Poly(3,4-ethylenedioxythiophene:polystyrene (PEDOT:PSS) based printed temperature sensor on a flexible PVC substrate. The temperature sensor was characterised using a digital multimeter for a temperature range from 25¤C to 90□C. The sensor showed a 70% change in resistance for the tested temperature range. Further, the sensing part was integrated with a Near Field Communication (NFC) tag with the data obtained semi-quantitatively by means of the intensity of an Light Emittign Diode (LED) connected with the antenna system. In this case, the antenna works as an energy harvester to power an LED indicator connected in series to the resistive temperature sensor. The intensity of the LED, which varies with the increase of temperature, was measured using a lux-meter mobile application. The intensity at 70□C was ~42 lux whereas it decreased down to ~14 lux at room temperature (~25□C). The presented system showed potential use as a smart label in applications requiring temperature monitoring.

A microplasma has been developed on a polymeric substrate for potential use in Chromium (Cr) speciation studies. Such proposed studies involve use of modified graphene oxide for selective chemical-removal and for mechanical-support of the removed Cr species on modified graphene oxide. Removed Chromium is measured using a microplasma.

The smart bandage is powered wirelessly by Radio Frequency (RF) energy based on NearField Communication (NFC) Radio-Frequency Identification (RFID) technology which also communicates the measured temperature and humidity data. A smart bandage in this form provides simple wound monitoring for the user at home and healthcare professional to monitor groups of patients. Investigations have been undertaken on antenna design, circuit design and bandage system integration. Fabrication is based on photolithography and etching of a copper coated Kapton.

Steady State Visual Evoked Potentials (SSVEPs) are a characteristic brain pattern that emerge in the Electroencephalogram (EEG) when a light source is flashed at a user. The EEG signal oscillates at the stimulation frequency, and this process forms the basis of many Brain-Computer Interfaces. This paper presents flexible inkjet printed sensors for the recording of SSVEPs. The flexible sensors obtain a capacitive connection to the body with an adhesive layer all the way under the electrode for maintaining a good body contact. The result is that SSVEPs can be recorded from behind a single ear without the need to use a conductive gel to lower the body connection impedance. The behind-the-ear location makes the electrodes very suitable for use in hearables and similar socially discrete wearable sensors for providing long term out-of-the-lab Brain-Computer Interfaces.

This paper presents a 3D printed robotic hand designed to have two capacitive touch sensors embedded in the distal phalanges of the fingers. Additionally, the readout electronics have been designed and fabricated to obtain the digital values of the capacitances and to use this data for touch feedback control. The touch or pressure sensors were fabricated by 3D printed electrodes using copper based conductive filament and a two part-rubber as the dielectric. The sensitive rmgertip was tested with dynamic and static stimuli and the average sensitivity of the sensors was found to be 0.6% N-1. The proof-of-concept robot hand developed here shows that the concept could be applied to develop the 3D printed embedded sensorised systems or instrumented objects needed for applications such as internet of things and human-computer interaction.

In this work we present a polymer-based flexible strain sensor integrated with an NFC tag to detect strain by means of a visual LED indicator. The sensor was fabricated using conductive polymer poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) as an active material inside a flexible and transparent polymer Polydimethylsiloxane (PDMS) microchannel. The strain sensor changes its resistance at different bending conditions, showing up to three order increase in resistance for $sim 100$ bending. A custom-developed passive NFC tag with an LED connected in series to the strain sensor is powered from an NFC reader to detect strain in a semi-quantitative way. The light intensity of the LED indicator is modulated according to the strain level, showing maximum brightness $(sim 67$ lux) for relaxed or no strain condition, and being almost OFF $(sim 8$ lux) for the maximum strain condition. The potential application of the NFC-based strain sensor system in food package for spoilage detection is also presented.
