In the operating theatre, innovations in sensor-enabled surgical tools are changing how surgeons identify tissue, monitor physiology and close wounds 鈥� improving safety, shortening procedures and reducing downstream costs for health systems. Innovations in catheter ablation devices, for instance, are transforming the landscape for cardiac arrhythmia management. Specifically, pulsed field ablation (PFA) involves using a catheter to deliver rapid, high-voltage pulsed electrical fields to heart tissue as opposed to the thermal energy used in traditional ablation. Different types of cells have different energy thresholds, enabling some to be ablated while others are protected. According to the Mayo Clinic, this technique reduces the risk to nearby structures such as the oesophagus, potentially providing safer, shorter and more successful procedures.
Modern surgical techniques such as PFA often rely on sensor integration, from magnetic sensors that provide real-time 3D mapping of the heart鈥檚 chambers, helping to guide the catheter to the target ablation site, to contact forces that measure the amount of pressure the catheter applies to heart tissue, ensuring stable contact. Electrical sensors may also be used to map the heart鈥檚 signals, identifying the arrhythmia鈥檚 origin and confirming successful ablation of the target tissue.
Below, we summarise further trends in smart surgical instruments and notable device examples, explaining how they work and highlighting the benefits for providers and patients.
Smart cutting and sensing: scalpels that 鈥渇eel鈥�
Traditional scalpels rely solely on the surgeon鈥檚 skill and visual cues. Sensor-enabled scalpels augment that skillset by integrating sensors into the blade or handle. These devices can detect subtle changes in tissue stiffness and moisture and distinguish healthy tissue from tumours, nerves or vasculature. For example, impedance-based sensors apply a small alternating current and measure resistance; malignant tissue and nerves often show reproducible differences versus surrounding tissue. When combined with haptic or visual feedback, surgeons receive real-time warnings that reduce accidental cuts to critical structures. The practical benefits include fewer intraoperative complications, less collateral damage and potentially shorter operations.
Tactile laparoscopic instruments
Minimally invasive (laparoscopic) tools traditionally remove much tactile feedback, increasing risk of tissue crush or improper suture placement. Embedding load cells, strain gauges or capacitive tactile arrays into forceps and graspers restores a sense of 鈥渢ouch.鈥� Some systems display a stiffness index or supply force limits directly on the console, enabling precise manipulation of fragile tissues. The clinical impact is improved ergonomics and fewer tissue injuries 鈥� advantages that translate into lower postoperative morbidity and shorter hospital stays.
Smart sutures and wound monitoring
Sutures are evolving from passive closure devices into active wound-management platforms. Smart sutures incorporate micro-scale conductive paths, piezoelectric fibers or integrated electronics to monitor tension, pH, moisture and inflammation markers at the incision site. Some prototypes also enable local drug delivery 鈥� releasing antibiotics or anti-inflammatories when sensors detect early signs of infection. By providing early objective data on wound healing, these sutures can reduce readmissions for wound complications and allow earlier safe discharge or targeted outpatient follow-up.
Materials enabling the next wave: why electroconductive LSR matters
As smart surgical instruments proliferate, many designers are running into a persistent engineering challenge: finding effective electroconductive materials that are simultaneously soft, stretchable, biocompatible, and manufacturable at scale. Conventional metal traces and hard plastics limit conformability and can increase the risk of tissue irritation. That is why electrically conductive liquid silicone rubber (LSR) materials are gaining traction. Conductive LSRs combine silicone鈥檚 long-established biocompatibility, chemical resistance and thermal stability with embedded conductive fillers (e.g., carbon nanotubes) to create flexible, low-resistance paths suitable for stretchable electrodes, sensor housings and integrated conductive sutures. Liquid injection moulding of LSR also enables high-precision, high-volume production of small and intricate parts critical to surgical instruments.
The development of electroconductive LSR represents a practical materials trend that lowers barriers to adoption. It facilitates miniaturised, sterilisable, and comfortable devices that maintain conductivity under deformation.
