Abstract

Purpose

The purpose of this paper is to propose a method for adopting an Internet of Things (IoT) enabled product-service system (PSS) considering business model and product enhancements. The method focusses on business process implications of IoT. The paper also discusses a real application of the proposed method to the machinery industry.

Design/methodology/approach

Considering the IoT technologies available, failure mode and effects analysis is applied to identify what should be monitored in the product to minimize potential product failures. In parallel, in order to assist the company in deciding which PSS strategy to be followed, a Configurator of PSS proposals is applied. The results are derived to define the IoT architecture and the business process design supported by the selected IoT technologies.

Findings

The main findings include the proposed IoT-enabled PSS adoption method, illustrated by the description of the application and its assessment. In addition, the identification of key process areas that are impacted by IoT is offered, namely: remote machine setup; corrective and predictive maintenance; material supply; product pricing; and information reporting.

Research limitations/implications

The application of the method proposed is limited to one company. Future work includes extending the application of the method to other units of analysis.

Practical implications

The method proposed can be considered by companies willing to increase product-service revenues based on IoT technologies.

Originality/value

The IoT-enabled PSS adoption method is an approach grounded on the intersection theories of PSSs and the more technology-oriented IoT developments.

Abstract

Purpose

The synergistic effect of functionalization of multi-walled carbon nanotubes (CNT) using KMnO4 oxidation and initial tensile deformation on the electrical resistance of nanotube network/polyurethane composite subjected to elongation was studied.

Design/methodology/approach

Though the initial deformation irreversibly changed the arrangement of carbon nanotube network, subsequent cyclic elongation confirmed stable resistance values. The increased strain-dependent resistance of stimulated nanotube network/polyurethane composite was demonstrated by monitoring vibration of tambour leather after a bead impact and finger flexion.

Findings

The results showed a tenfold composite resistance increase for the composite prepared from KMnO4 oxidized nanotubes, quantified by a so-called gauge factor, from a value of about 20 in comparison to the network prepared from pristine nanotubes. This is a substantial increase, which ranks the stimulated composite among materials with the highest electromechanical response.

Originality/value

The results in this paper are new and have not been published yet. The paper combines different ideas which are developed together. It presents a new concept of synergistic effect of CNT oxidation and application of pre-strain simulation. Oxidation and pre-strain increases by several times the sensitivity of the tested composites which are predetermined for use as strain sensors of various sizes and shapes.
