Open OpportunitiesGroundwater resources are an important source for the drinking water supply of the city of Zurich and its neighboring communities. The Hardhof groundwater well field in Zurich has been in operation for over 70 years and supplies groundwater to households from 4 large horizontal wells. Through an active control method these wells need to be shielded from the on-flow of groundwater of lower quality stemming from the city. - Civil Engineering, Environmental Engineering, Mechanical and Industrial Engineering

| Photochemical reactions are playing an increasing role in tissue engineering and biofabrication fields. Phototunable hydrogel with programmed properties that allow controlling cell behaviors spatiotemporally. This project aims to develop a series of photosensitive hydrogel precursors and study their structure-property relationship systematically. - Chemistry, Engineering and Technology, Medical and Health Sciences

| There is a massive underground network of sewers beneath the city of Zurich. The sewers, which transport rainwater (stormwater) and sewage (blackwater), must be maintained to prevent clogging and the build-up of sand which can affect the flows and ultimately, treatment. Currently, Entsorgung + Recycling Zürich (ERZ) sends teams of workers into the sewers to perform preventive and reactive maintenance, which often involves the use of high-pressure water. The work is difficult, smelly, and loud: workers must navigate small openings and work under difficult conditions while also ensuring their own safety and maintain communication with each other and the ground. Unfortunately, because of the depth and high noise levels, radio communication is not possible. Currently, lights, whistles, hand-signals, and other informal techniques are used to communicate between workers, but these methods are prone to failure and misunderstandings. - Engineering and Technology

| Together with the Schulthess Clinic, the Sensory-Motor Systems Lab, ETH Zurich, has developed the mHIRex which, based on the common clinical manoeuvre, precisely determines the force required for internal hip rotation. The next step would be to assess hip internal rotation in a large cohort of consecutive patients with hip disorders. - Biomechanics, Clinical Engineering, Clinical Sciences, Sports Medicine

| Bio-waste (also called organic waste or green waste) can be used as a sustainable feedstock for the production of biogas: an alternative energy source. However, In order to be efficient, a biogas plant must process large amounts of organic material. Currently, Entsorgung + Recycling Zürich (ERZ) processes bio-waste from households that is stored in special green containers and collected weekly with compactor trucks. This material then gets converted into biogas (or compost) at the fermentation plant.
As each green bin serves numerous households and is quite deep (approximately 1.5m), liquids seep down and pool at the bottom, while other particles may stick to the container walls. When ERZ arrives on site, the containers are emptied into the trucks and later placed back to their original location, but without cleaning them. Cleaning is either left to the landlord or done with a specialized vehicle, but is rare, and the containers may become less appealing to use over time.

| This project aims to develop interpretable machine learning algorithms to understand the relationship between physical and psychological aspects of pain, through the identification of reliable biomarkers that consider pain in all its multidimensional aspects, towards an optimal diagnosis and personalized therapies.
Chronic Pain patients will be monitored during at-home multiday experimental protocol. During this time, they will be asked to wear a wearable device collecting multiple physiological data and to complete comprehensive assessments through psychological and life-quality questionnaires. Machine Learning models will be applied to disentangle the physical and emotional components and to correlate pain perception with sleep quality and medications.

| This project aims to evaluate how emotional and cognitive contributions, introduced using different virtual reality scenarios, change the subjective pain perception. We aim to conduct a study comprising Transcutaneous Electrical Nerve Stimulation (TENS) and Virtual Reality (VR). TENS will be used to induce short painful stimuli while VR will be used to modulate the cognitive and emotional inputs by presenting different inputs (e.g., fire/electricity vs water stimuli on the virtual limb). Several physiological measures (EEG and multisensory wearable) will be collected together with the subjective pain perception. Machine Learning will be applied to physiological data, to disentangle the physical reaction to pain with respect to psychological components. - Biomedical Engineering, Neurosciences

| In the city of Zurich, the locations of the recycling collection points (RCP) are not digitally recorded and there is no geo-information system in which the locations are recorded. In certain areas (e.g. Höngg) there is also an undersupply and the affected residents do not have easy access to the RCP (e.g. not within walking distance). Entsorgung + Recycling Zürich (ERZ) would like to remedy the existing undersupply and to show the existing RCP in a digitalized and possibly interactive map.
At the same time, the city of Zurich is growing and new housing developments are constantly being added, triggering additional demand for RCP. Due to other urban developments, it may also happen that existing RCP have to be deconstructed. Currently, no planning model exists to identify or predict optimal RCP locations.

| Entsorgung + Recycling Zürich (ERZ) provides a variety of waste collection services for the citizens and companies of Zurich; one of the services is an on-demand collection of bulky waste by compactor trucks. The trucks are equipped with a weighing system for standardized containers, which can be handled by the container tipping mechanism. Unfortunately, single pieces of furniture (e.g. sofas, tables, etc.) cannot be weighed. Thus, ERZ is forced to charge the customers by loading time instead of weight of the collected material.
In order to implement a more suitable calculation of costs, ERZ is interested in finding a method to weigh single pieces with the same scale used for the weighing of the containers.

| Entsorgung + Recycling Zürich (ERZ) manages more than 4100 public waste bins of different designs throughout the city of Zurich. Considering the large number of waste containers that get emptied every day, efficient workflows are extremely important. In the case of the public waste bins, the removal of full bags and the replacement of new bags in the waste receptacles is time-consuming and inefficient. While the full bag can be removed rather easily, the placing of the new bag can be a cumbersome process. ERZ strives to continuously improve ergonomics and optimize the workflows. Therefore, it is investigating better solutions for the bag replacement cycle. - Engineering and Technology
