Next generation implantable devices

The healthcare sector is changing to embrace the inter-connectivity of the Internet of Things for more proactive patient health management. The rapid development of sensing devices for Wireless Body Area Networks is opening opportunities for continuous health monitoring in the patient’s home or place of care provision. Increasingly energy-efficient, these sensors are following a trend towards miniaturisation being deployed in implantable or on-the body devices including neurostimulators, leadless pace-makers, smart contact lenses and pulmonary blood pressure monitors. These devices treat many conditions such as Parkinson’s diseases, Dystonia, chronic pain, OCD, tremors, diabetes, cardiac conditions. In most cases, a solution needs to be provided to power these devices autonomously or wirelessly which requires small size, energy storage components.

  • Miniature size, mm-scale and sub-mm thickness
  • Long life: devices won’t be de-planted because the battery has died early
  • Energy density: M50 can be stacked to increase capacity whilst still being less than 1 mm thick

Leadless pacemakers

Current pacemakers are bulky devices placed inside the chest muscles and connected to the heart with two leads directed inside the heart itself. If the device needs to be replaced, for example because the battery has run out, two new holes need to be created to insert the two new leads, which may lead to infections or worse. Next-generation pacemakers will be leadless and implanted directly inside the heart via a big artery. This requires the whole pacemaker, and of course the battery, to be extremely small and thin.

  • Ultra-thin, elongated form factor
  • Long life: devices won’t be de-planted because the battery has died early
  • Low self-discharge: won’t waste energy provided via wireless charging or harvested energy

Smart contact lenses

Ocular contact lenses are becoming smarter. A variety of sensors are being miniaturised and integrated onto contact lenses in order to guide medical treatments for conditions such as glaucoma, diabetes or presbyopia. Other developments are also taking place in the area of augmented reality with miniature built-in cameras being tested. To provide power to these new electronic devices, an energy storage component of minimal footprint and thickness is required.

  • Ultra-thin: only a few hundred microns
  • Miniature footprint: can be designed to be a few mm2 only
  • Low self discharge: efficiently stores energy provided by energy harvester (for example a small solar cell) or wireless charging

Neurostimulators

Neurostimulators are small medical devices implanted inside the body, more precisely onto the Vagus nerve (at the back of the neck) or other parts of the peripheral nerve system. They provide small electrical impulses which have shown to remedy or ease a large number of conditions from Parkinson’s disease, Alzheimer's, epilepsy and more generally migraines, depression or chronic pain. Current devices consists of electrodes placed onto the nerve or spine, which are powered and connected to the pulse generator on the lower back with wires implanted under the skin. Next generation devices will simplify the procedure by having power and communications all integrated in one single small device right next to the electrodes.

  • Miniature size, mm-scale and sub-mm thickness
  • Long life: devices won’t be de-planted because the battery has died early
  • Energy density: M50 can be stacked to increase capacity whilst still being less than 1 mm thick

Industrial Internet of Things (IIoT)

On-wafer sensing

In semi-conductor or MEMS foundries, the environment in which silicon wafers are being deposited needs delicate control. The temperature must be absolutely correct to maximise deposition and growth. However, wiring sensors inside the deposition chambers is not practical as these chambers are typically pumped down under low vacuum. Sensors are instead integrated on sensing wafers which can be inserted in the chamber just before deposition. Temperature is also relatively high and can reach 150°C or more. Using conventional batteries for powering these sensors is not convenient as most conventional batteries can not operate above 70-80°C.

  • Can operate to 150°C continuous temperature
  • Ultra-thin
  • Can power BlueTooth Low Energy or other low power wireless protocols

Condition monitoring of assets

The vision of Industrial IoT, or Industry 4.0, is that of interconnected machines, services and people. Within this vision, the real-time knowledge of the operational health of assets in the manufacturing environment is possible. Using sensor end nodes, an algorithm can continuously monitor the frequency signature of vibrating pieces of equipment such as pumps, or the temperature of manufacturing machines like evaporation chambers. This enables prediction and scheduling of maintenance and repair before costly downtime occurs. However, in many cases, these sensors may need to be retro-fitted in difficult-to-reach places making it impossible for them to be easily wired in, or in hostile environments of temperature or moisture where common batteries cannot operate.

  • Can operate to 150°C continuous temperature
  • Ultra-thin
  • Can power BlueTooth Low Energy or other low power wireless protocols

Active asset tagging

Throughout the life of a product - from component sourcing to manufacturing, from shipping to storing - it is crucial to understand where and in which conditions products have been placed. Asset tagging of products using RFID is a simple solution but tags are required to become smarter and more active so they can actively transmit key data, such as their position and what temperature they have been stored at. In hospital environments for example, equipment can be difficult to locate and small detection devices are being developed that will be placed on the mobile apparatus and ping its position without the concern of the battery running out of power.

  • Can power BLE, Zigbee or longer range communication protocols with additional capacitor
  • Can be recharge efficiently with harvested energy such as solar or vibration
  • Ultra-thin

Powering the oil and gas industry into Industry 4.0

IoT offers the oil and gas industry many benefits including real-time analytics enabling management of critical processes, data to implement predictive maintenance programs and remote control of equipment to improve safety. But it also faces many challenges. Many assets in this industry are in hostile environments, especially down-hole drilling where small sensors are placed on the end of the drill bits to measure temperature, pressure and other parameters related to the rocks or fluids in the hole. These sensors, and their method of power, need to cope with temperatures up to 150°C, be reliable and long lasting. Ilika has developed a solid state battery, the Stereax P180, that can power IoT sensing devices over a wide operating temperature window.

  • Extended operating temperature from -40°C to +150°C
  • Thin form factor
  • Stackable batteries with high energy density

Automotive

Tyre Pressure Monitoring System (TPMS)

Application NotesTyres are getting smarter.Whilst current TPMS normally only measures tyre pressure, next generation devices intend to provide much more information to the driver, such as the condition of the tyres, possible wear, temperature etc… In current TPMS, either placed in the thread or more recently in the rim of the tyre, coin cells are used. This makes TPMS more bulky than they need to be and difficult to replace the battery if it fails. A solution combining a miniature solid state battery with a vibration energy harvester could provide a long term, perpetual device.

  • Low leakage stores harvested energy efficiently
  • High energy density
  • Small size

Solid state batteries for electric vehicles

It is widely accepted that CO2 emissions are a global environmental concern and that electric vehicles will help reduce this. However, whilst people are increasingly interested in hybrid and electric vehicles, fear of too short driving range and long charging time are making them hesitant to convert to one. To address this problem, Ilika is developing high energy density, rapid charging and safe solid state batteries in our "Goliath" project.

  • Non-flammable solid electrolyte
  • Much faster charging times (under 10 minutes)
  • Increased energy density (>500 Wh/kg)
