“…At higher fluence and number of pulses broad bands assigned to the D band of amorphous carbon and the G band of polycrystalline and microcrystalline graphite also appear (Fig. 2a), confirming findings described before [9,10,14,15]. Moreover, spectra variations are XPS and l-Raman analyses are conducted about a month after the laser treatment.…”

“…(iv) An increase of Si in the EDS spectra was observed acquired on PDMS irradiated with Nd:YAG laser in comparison with those on native PDMS [10]. Laser treatment is used in order to facilitate selective metallization of the areas activated in this way [11][12][13][14][15].…”

“…The sharp peak between 512 and 518 cm À1 appears also in the case of processing with visible light (VIS) of nanosecond Nd:YAG laser (532 nm) and femtosecond laser (527 nm), which is the first observation of c-Si formation by irradiation of PDMS with VIS femtosecond pulses [15]. This can be ascribed to mono and/or polycrystalline or only to monocrystalline silicon (c-Si) [16].…”

“…Its intensity increases with the number of the pulses and the laser fluence. Moreover, in the l-Raman spectra broad bands appear between 1320 cm À1 and 1603 cm À1 depending on the experimental conditions, which can be assigned to D band of the amorphous carbon and the G band of polycrystalline and microcrystalline graphite, respectively [9,10,14,15].…”

In this paper, the variations in surface structure of polydimethylsiloxane elastomers before and after argon plasma treatments have been investigated by X‐ray photoelectron spectroscopy, slow positron beam, and scanning electron microscope. An inorganic silica‐like layer was probed by X‐ray photoelectron spectroscopy after 3 minutes or longer time of treatments, and the sample surface turned into totally hydrophilic. Short time (1 and 2 min) plasma exposure mainly removed preexisting low molecular weighted (LMW) siloxanes on sample surface. By using slow positron beam, the thicknesses of silica‐like layer for 3‐, 5‐, and 10‐minute–treated samples were estimated to be around 30, 66, and 91 nm, respectively. Beneath the silica‐like layer, a loose polymeric structure was also detected, which was ascribed to the accumulation of LMW siloxanes. Scanning electron microscope images showed that the silica‐like layer cracked after 10 minutes of plasma treatment, which provided direct diffusion pathways for LMW siloxanes. Hence, 10‐minute–treated sample showed rather low organic composition near surface. Slow positron beam provides valuable depth profile information for evaluating the surface aging condition of polydimethylsiloxane composite.

Laser Direct Writing of Highly Crystalline Graphene on Polydimethylsiloxane for Fingertip‐Sized Piezoelectric Sensors

The patterning of electrically conductive structures directly onto the polydimethylsiloxane (PDMS) surface is crucial for the realization of flexible and elastic devices. Herein, defocused femtosecond laser pulses are irradiated for the fabrication of highly crystalline graphitic carbon structures on PDMS and a high electrical conductivity of %51.6 S m À1 is achieved. Utilizing the elasticity of PDMS and the high conductivity of fabricated structures, a fingertip-sized pressure sensor, which can detect pressures as low as %0.1 Pa, is realized. Moreover, a novel ring-shaped heart rate (HR) monitor, capable of measuring the HR from the index finger, is demonstrated, indicating the potential of fabricated structures in miniature and wearable healthcare applications.
