The Bendable Electronics and Sensing Technologies (BEST) group has developed innovative products that are in the process of entering the market. BEST group members have participated in the iCure 3-month journey to learn from customers and prepare a business plan for these products. Find out more about these exciting technologies below.

Flexible Supercapacitor

Opportunity

The Bendable Electronics and Sensing Technologies (BEST) Group, led by Professor Ravinder Dahiya have developed a novel, flexible supercapacitor (SC). The Group have overcome the traditional drawbacks of supercapacitors by achieving a significantly higher potential window, energy/power density, longer discharging and cyclic lifetime and enhanced stability combined with the key enabler that the SC is flexible. Those characteristics make this flexible supercapacitor a platform for many applications, including autonomous vehicles.

 

Key Benefits

  • Maximum energy and corresponding power densities are 10.22 μW h cm-2 and 11.15 mW cm-2 at a current density of 10 mA cm-2
  • Operating voltage of 2.25 V.
  • Suitable for high power applications: a power density up to 22.63 mW cm-2 (at the current density of 24 mA cm-2) corresponding to an energy density of 6.2 µW h cm-2.
  • The observed capacitance (15 mF cm-2) and the maximum operating (~2.5 V) voltage in an aqueous H3PO4
  • Stable response, with initial and final 10 cycles from a total of 106 cycles showing only 0.2 % of variation in capacitance.
  • Highly stable and tested over > 15000 charging/discharging cycles at operating voltage and current densities of 2.5 V and 10 mA cm-2.
  • Solution resistance of < 15 Ω at high frequencies.
  • Under bending radius of 15, 20 and 25 mm at an applied current of 1 mAcm-2 and also under dynamic cyclic bending (bending radius of 24 mm and 100 cyclic bending) the SC shows no significant change in the performance.

 

Application

We see one primary application for the technology in autonomous vehicles, which Elon Musk has placed significant importance on SCs: “If I were to make a prediction, I’d think there’s a good chance that it is not batteries, but super-capacitors.”

Given flexible innovation, the SC has many potential applications including in wearables, robotics, e-skin are all potential applications and we are open to exploring all opportunities

 

Stage of Development

The University published a high impact academic paper and is in the process of filing a patent for the technology. The University is searching for co-collaborators and licensees for the technology.

Holographic Display with Touch Interface

Opportunity

The holographic display with touch interface was developed by the Bendable Electronics and Sensing Technologies (BEST) Group, led by Professor Ravinder Dahiya. Interaction in the real world involves 3D vision, touch and tactile/haptic feedback. An interactive 3D hologram could bring these experiences together in an effective way with major applications in sectors including the multi-billion-dollar entertainment and gaming industry, education, and medical areas. Our system can provide an interactive holographic experience where the holographic projections can be manoeuvred by directly interacting with the hologram in mid-air with hand gestures similar to real world object manoeuvring. 

 

Key Benefits

  • Embodies novel configurations of touch and 3D gesture interactive display.
  • System could give the feel of temperature to heighten the experience.
  • The system is scalable to be used for large-scale Pepper’s Ghost displays.
  • No need for special glasses to experience 3D imaging.
  • Multi-touch in the secondary display: NIR Camera-based multitouch detection system which can detect action of touch in the secondary display.
  • 3D Gesture detection: Free hand gesture detection inside and outside the angular enclosure. This is possible because of the novel configuration.
  • Aerohaptics: Aerohaptors (plurality of air source elements) primarily directs air to a particular location for sensory feedback to a part of a user’s body in a particular position. The feedback could be force in one or more direction and temperature.
  • Voice Recognition.
  • Computer programs & apps connecting all of them.

 

Applications

This interactive system has potential applications in the entertainment and virtual reality industries but could also be extensively used in education, medical, engineering and public demonstration.


Transparent Tactile Skin

Opportunity

Researchers at the University of Glasgow have developed a graphene enabled tactile skin to be applied to robotics, prosthetics, healthcare and surgical instrumentation.

Tactile or electronic skin is needed to provide critical tactile feedback / haptic perception to robots and amputees as well as in wearable Systems for health monitoring and wellness applications.    

The electronic skin has a single layer of graphene coated with a polydimethylsiloxane (PDMS) layer on the sensor’s active area making the device sensitive to touch. Utilising the transparent nature of graphene, a PV cell embedded in the skin can harvest energy to power the electronic skin – a significant step towards energy autonomy of skin. This innovation has been demonstrated through the fabrication of e-skin, which has then been integrated onto a prosthetic hand to grab soft objects, and intensive characterization of sensors for static and dynamic stimulus. The work can be easily extended to applications such as smart windows, transparent touch screens and IoT.

Key Benefits

  • The tactile skin provides a similar sense of touch to robots and artificial prostheses by mimicking some of the features of human skin
  • Graphene has the properties as a viable candidate for various flexible transparent electronic and optoelectronic devices
  • High quality graphene can be synthesized and transferred on large area flexible substrates with a very low-cost and easy fabrication process
  • The developed skin can be easily extended to include energy storing devices.

Applications

There are a number of potential applications for the graphene enabled tactile skin including:

Prosthetics

  • Wearable patches for health / wellness monitoring
  • Rehabilitation Robotics
  • Transparent touch interfaces
  • Smart Windows
