The Netherlands is one of the leading countries in sensor technology. It is an industry that is developing enormously. Sensor systems become smaller, faster and more accurate and they are used in an increasing variety of products. They can for example be used in autonomic devices such as machines, tools and consumer products and for the recording of human movements.

The start-up JimFIT has developed a wireless, portable and mobile sensor system that can measure movements. The entire system includes a sensor system and an app. With support of the app data can be translated into relevant information for the user. Furthermore, the app will also give feedback to the user. The sensor system of JimFIT can be used in the sport sector and focuses on the consumer market.

NNTS is developing a prototype that is ready for mass production. The hardware and back-end software will also be developed.

Due to increasing objectives of reducing CO2 emission and gas consumption, municipalities are looking for possible sustainable energy sources. The municipality of Enschede is also exploring its options.

The municipality of Enschede wants to investigate the use of geothermal energy as its durability is beyond dispute. Before starting costly drilling activities and the technical elaboration, NNTS will start with a feasibility study that includes the technical and financial aspects.

The goal is to deliver a consultancy report that is based on the potentials of geothermic heat and the possible consumption profile. Technical aspects, financial effects and possible risks of deep geothermal energy in Enschede are taken into account and will be discussed in different scenarios.

"In 2017, NNTS conducted an investigation into the (financial) feasibility of geothermal energy in Enschede, commissioned by the municipality of Enschede. In this research we have gained good experience with NNTS. Project leader was Nathan Baak, and where necessary supported by Jurre Kuiper.
 
Driven young people, with a sharp insight into the problem, and able to acquire knowledge from the right people and organizations. Able to include both the officials involved and the directors and councilors involved - who are no experts in this area - in this matter. A lot of attention for clear presentation, both in presentation tools and in explanation. Planning and meeting deadlines also agree." - Anne-Roos de Bloois (Municipality of Enschede)

Description

The biggest bean sprouts plantation of Europe, Evers Specials, asked NNTS to design a new packaging method in the production of bean sprouts. Evers Specials has a completely automated production line, which makes it a challenge to fit the new packaging into the current production and packaging process.

Due to the high number of packages the cost of the packaging needs to be taken into account, as a marginal increase in base price means a significant increase in costs.

Because of these challenges, the design will be focused on a simple but effective new packaging for bean sprouts.

Description

Boers Techniek has been commissioned to produce a machine that can test artificial turf for FIFA. The machine has a number of functions, including simulating the studded soles used by football players. This simulation is done with a studded roll that exerts a force of 95 kilogram and is rolled over the turf.

NNTS was asked to prepare the roll, that has been designed for this purpose, for production. The studded roll is produced with a specialised 3D printing technique called SLS. For this technique to work, it is necessary to segment the roll in the correct way without intersection in the studs. NNTS performed this segmentation, prepared the roll for production and worked together with a suitable producer to supply a satisfying result for Boers Techniek.

Description

The use of prescription drugs keeps rising both among youngsters and elderly. For both groups it is important to take their medication on time. There are different ways to remind people of this, but the technology is too complex for the elderly and too fragile for children. A dedicated device with a specific function can offer the solution.

The start-up Tubanti has the idea to make it easier to remember certain actions with a (wrist)band. NNTS designed the first prototype of the wristband and developed the hardware and software. Different target audiences were taken into consideration, determining specific functions and appearance. In the end, a prototype design of the wristband was delivered along with a hardware schematic made in Eagle and validated software developed with model-based programming.

Description

Everything needs to be more sustainable and energy efficient, including wastewater collection in rural areas. The new so called "Druk Vacuüm Compact (DVC) systeem", or freely translated Compact Pressure Vacuum system, uses a vacuum tank to collect wastewater from a pressurized wastewater system. Eliminating the need for pumps in every manhole, this system reduces energy consumption and costs. One of the challenges in developing a system like this is designing a reliable mechanical valve that is able to work under the circumstances found in sewers.

NNTS was involved in this project for the development and validation of prototypes of the mechanical valve. To be able to test these, a test installation was built and multiple prototype designs were produced and tested by NNTS. The project yielded two validated prototypes and a number of recommendations for further development. These results are taken into account when deciding whether further research is warranted for the DVC system as a cost effective replacement for the pressure sewer.

Description

For the design of a new type of heat recovery, a project is carried out in which a theoretical model has been made to calculate the possible heat recovery from gravity sewers. This model will enable the client to make a quick and fairly accurate approximation of the design possibilities. The model is made through theoretical research, can be used for feasibility studies and is a great tool when making a detailed design.

The model also includes an extensive heat pump analysis tool in which the relation between the heat exchanger in wastewater and the heat pump is stipulated. This way the calculations for converting the temperatures from waste heat to usable heat are performed instantly and time can be saved in the design process.

Description

NNTS carried out a project in which a hydraulic/pneumatic system is designed to drive a mechanical component. The challenging conditions include high temperatures, high speeds (~100.000 rpm) and limited space.

A theoretical research was performed to determine the pressure losses for different solutions, followed by the design of a prototype for the theoretically most feasible solution. The prototype will be used in tests to deliver a technical proof of concept.

Description

This feasibility study was aimed at using residual heat from hotels that is normally lost to the sewer. A lot of heat is wasted in hotels where hot water used by sanitation and kitchen appliances is flushed away at high temperatures.

The first phase consisted of researching different alternatives for which different setups were modeled regarding the heat pumps. Also, a short research was performed on pollution of heat exchangers and its effect on heat recovery.

In consultation with the client, one preferred alternative was chosen and is further developed and analysed. In order to give the client an idea of the possibilities, a financial feasibility study including cost-benefit analysis for different sizes of hotels and different usage profiles has been performed.
